  1. 5 Star Rising,   I hate to be the bearer of "Bad News" but  if your measurements are correct, a proper repair is beyond most home mechanics.  I am a ASE Certified

    Automotive Body and Paint Repairman.   Your damage is to great to just slot brackets and achieve proper alignment.    I would say your best best is get a repair estimate

    from a Body Shop in your area.   But fixing the car and not damaging the paint job might not not be possible.  I hope this advise helps.

  2. Battery Box Modifications-

         This is the Delco Replacement Battery for a 2019 Chevrolet Corvette 6.0L LS3.

    It is a GelCell Battery rated at 900CCA but weighs 49 pounds.   Because of its weight and size, I decided to beef up the original Battery Tray.

    Making a Paper Template of New Battery Tray

    IMG_E3523.JPG.4012a2153c3bec2af7ee06334bdf2a1a.JPG

     

    I decided to construct the Battery Box out of 16 gauge Stainless Steel.

    Used Right Angle Grinder with cutoff wheel to cut the Stainless Steel.

    After Bending the Stainless Steel and tack welding the two

    front corners, the Battery Box looked like this.

    Added two Holes on side for Improved Appearance.

     

    Made a Paper Template to locate the Mounting Holes for the

    Battery Box.

    Template taped the Bottom of the Battery Box to locate holes to be drilled.

     

      Three 6mm bolt and nuts installed in Firewall to support the Box.

    Four 5/16" Carriage Bolts and nuts secured the Box to existing

    Battery Tray.  The Box was polished with Buffing wheel.

    Battery Box with Stainless Steel Hold Down Bolts.

     

    Unfortunately, when I tried to put the Delco Battery into the 

    New Battery Box, it would not go in.  The Left Side Box Wall prevented the Battery from sliding in.  So that Wall had to be 

    removed.

     

    Modified Battery Box Version-2

    This Second Version shows no matter how careful you plan

    something, it can go wrong.   So You must be able to adapt

    and continue.

     

    Next-More Wiring to do

     

     

     

  3. Change  of Plans-

     

         I must have been a "Good Boy" because my Ungraded Holley Terminator X Max arrived on Christmas Eve.

       Brand New Holley Terminator X Max# 555550-910 was designed for Late Model LS3 motor with 58 CAM, EV6 Injectors, Drive by Wire Throttle Body and a Remote 3.5 Touch Screen Turner was $1540 from Amazon.

    IMG_3762.JPG.9d83797d6de2614a3a69c4dd48f6813b.JPG

     

    IMG_3410.JPG.6923be4a183be1331276c4bb9bb74a9a.JPG

     

    IMG_3412.JPG.5f83c8b940ea9b81cdc9e669b30df437.JPG

     

       I started by laying the Holley harness over the motor and attaching the sensors.   Everything pretty much lined up but there were wires which were a little

    short.  But no big deal.  A little shifting of harness around and  removing the tape on the looms to gain an inch or so. Then,retaping the hareness.   With the harness laid out,  I could tell the major problem would be getting the harness through the firewall to connect to the computer.

        The area between the Battery Tray and Firewall was the only place where everything would fit.  Local Reconstruction Law did not allow relocating the battery into the rear of the car.   Although that location would make harness routing much easier with no battery in the way.   Plus, Weight Distribution would be better too.

    IMG_3598.JPG.31ff91d1bc7d794d0f6f0211ab28f37f.JPG

    This was a small Area for alot of wiring to pass through.   The holes under the battery tray was for the AC Hoses to pass thu.

       I found this Split-Seal Grommets that was big enough but stll provide good sealing qualities.   But they costed $35 each from Amazon.

    seal IMG_3711.JPG.1454c88a6f3ecdb0b6ae46c920b59edf.JPG

            Note- The Split-Seal has extra sealing lip at the joint.  It provides a little more joint sealing.

            I also made an additional sheet metal ring to reinforce the seal from the interior

    side of the seal.   The Split Seal and Reinforcing Ring was bolted together with six 4MM bolts and nuts.

    IMG_3690.JPG.1c8905bfba684444cb78fc1db68fc131.JPG

     

    Cleco Pins were utilized to position the seal while installing.

    Aluminum Templates with various hole sizes were used to determine correct hole to be drilled in the Firewall.  The biggest objects on the harness were the various relays so the hole had to be at least this diameter so the harness could fit thu.

    IMG_3647.JPG.8850cdcdccc7538b5c4054808d905e09.JPG

           

    In case you need a custom Grommet , this is the procedure to construct one.

    IMG_3653.JPG.c9f7fa70dcbd8fbab9455d50c1996e22.JPG

     

    Cut out 23 gauge sheet metal to create the Outer Frame.  Use a razor or knife to make the  Round Seal out of 1/8" rubber sheet.

    .IMG_3656.JPG.6736ab33a875660d7065d32e33fdc39e.JPG

    Finish shaping and use Contact Cement to attach Rubber Seal to frame.  Then drill six Mounting Holes and cut seal in half.  If additional sealing is needed, just make an additional rubber seal on the Interior Side of the seal.

    IMG_3657.JPG.07a3ec493f98fe1c783efe892989a30e.JPG

    Note-It is important to make the Center Sealing Hole slightly smaller to provide a tight fit with harness.

     

    For Grommets for other Small Wires, you can use Grommets (from Home Depot).

    Use the ones made specifically for certain size sheet metal hole.   These seals are usually made of for use in sheel metal holes but check to be sure.

    IMG_3731.JPG.29945b4fbd4bee3f17356ff27af21f08.JPG

    If you want  a tight fit for individual wires, drill slightly larger holes than wire diameter and push wires thu individual holes instead of just slitting the grommets.  This method provides tighter sealing fit.

  4.    I was planning to post about installing the Holley Terminator X Engine Control Kit but at the

    last moment I decided to go to a upgraded version of the Holley Kit.   So that may take a couple of weeks to arrive because of the Pandemic and Christmas.  but there are still plenty work to do.

      

    Drive By Wire Accelerator Pedal Installation-

        Holley recommends  using  AC Delco # 10379038 Pedal  Assembly( Amazon-$88.   However, you have to fabricate your own mount.   Normally, accelerator pedal were easy to fab as they were usually constructed of 3/8"-7/16" steel rod.   One could just heat the rod red hot and bend it as necessary.  However, Electronic Throttle Pedals are constructed of 16 gauge metal and plastic pedal arms.   Thus, fabrication of the pedal mount is a lot more difficult.   Also, the location

    of the pedal is in a confined area next to the trans tunnel.

    IMG_3569.JPG.d89df544eef31acc20a819c0d55c1edc.JPG   Originally, the pedal would be attached to this plate on the firewall with three screws.

     

    I made paper templates to create the Pedal Mount.

  5. Engine Compartment Modifications-

     

         I forgot to post the Alternator that I utilized-NAPA #272-4717 104 AMP  Alternator( cost $130).   I originally tried to install a 140AMP GM one but it was way too large to fit in the bottom

    driver side of the motor.    I think 104 AMP is sufficient unless I install an Electric Power Steering Unit.   The NAPA Alternator has a Lifetime Warranty and 104 AMP is widely available.

    AIr Intake-

        My Crate LS3  6.2 Liter motor did not come with a Air Intake  Setup so I had to fab

    one.   Spectre Performance had a 4" Stainless Tube ($75), 36" 0fn 4" Flex Tubing($32)and 4" Right Angle Rubber Elbows(($24) for basis of my system.

    IMG_3409.JPG.19171bf25d5a70aee8ca221412d795eb.JPG

     

    I didn't want my Air Inlet to breathe Hot Engine Compartment Air so I fab the system to get Cold Air from just behind the grille.

    IMG_3465.JPG.58112912047f0200e34571698630737d.JPG 

    Had to enlarge the hole in the Core Support to accomplish this.

     

    Also, had to "Tap "  the Wheel Housing to get about 3/4" clearance for the Duct Hose.

  6. 12vt Cooling Fans

     

        To go with the Champion Radiator, Two Spal 12vt. Electric Fans and Shroud were installed.   The fans provide 1500 CFM of Air Flow but draw 27 maximum amperage.   The

    Two Individual 30 Amp Relay are triggered by a 185 Degree Thermo Switch in the engine block.

    Dual 30 AMP Relays triggered a 185 Degree Thermo Swuitch.

    I also added an Emergency Bypass Switch to turn on the Relays

    in case of Switch Failure.  Everything was mounted on the Right Side Wheel Well Housing.

     

    Alternator Mounting and Belt Arrangement-

         Originally ordered, a ICT Billet LS Motor Alternator Bracket from Amazon for $40. Unfortunately because my custom made Motor Mounts were located too far forward and the ICT Alternator Mount would not work.  So I had to fabricate my own alternator bracket.

  7. 5 Star Rising,

        By your description of different gaps on your Core Support and your Hood Height problems, you might have Twisted Core Support.

    To verify that conclusion, you must make measurements  of your front end.   Place your car on a flat hard surface.   Make your wheels in straight

    ahead direction.   Take measurements in inches or millimeters.   First, always measure from factory bolt holes vertically to the ground .    Start at the 10mm bolt attached to the front inside of the Ringt and Left Headlight housings.   Since this is the furthest bolt that is attached to the

    Front Core Support,  any body damage will show up as significant differances in your Right and Left Ground Height measurements.

    If the damage is not too bad , it still can repaired but probably need a body shop to do the work.  Please use measurements(in inches or

    millimeters)  to describe your problems.  This procedure will aid in determining how to fix your problem.

                                                                                                                            Tool Man

     

  8. 5 Star Rising,

            If your main concern is the hood pushing back after you push it down, your problem is probably with the hood hinges and/or torsion rods.  Note-if you have not removed your grille, you should as it will make easier to work on your hood and hinges

    But First, remove your hood and check for squareness. 

    IMG_3460.JPG.91881927139dea13b7dd7fa5e5c1af2f.JPG

     

    If your Hood is not within specs, the Hood is damaged and probably need to be replaced.

      

    Now, Remove the Hood Hinges and Torsion Bars.   Replace the Hood on the car.   Using shims( anything can be used) and attempt

    the "level" the hood as best as possible.   This method will demonstrate if the hood can be made level with your car.   If this can not be accomplished, the hood or car body is damaged.

       If the hood is level with the body, then the problem is with the hinges and/or torsion rods.   Remove rods from hinges.   Check both hinges and rods for damage and wear.  Open and close hinges-full movement-measure if necessary.   The rods are more difficult to inspect.   Place them close together.   Match the angles the rods on both rods.   Being Spring Steel , the rod angles should very similar but spring tension is hard to measure unless you have a spring scale( like fish weight scale).   If the hinges and/or torsion rods do not pass, replacement is necessary.   If the hinge and rods pass, the next step is Hood Adustment.   Replace Hinges but Rods off, this way you are 

    check the hinges only.  Adjust the hood(with no hood lock).   With hood level and square, mark the hinges so you can replace the rods.  If you can not adjust  the hinges at this point, you may have slot the hinges mounting holes.

     You have to use the step by step method otherwise you never solve the problem.

          If this method does not solve your problem, you might have a damaged front end but that can be checked so keep posting.

                                                                                                                                      Tool Man

         

  9. Bead Roller Modifications-

        After watching the video in my last post, you may have noticed that I made additional modifications to my Bead Roller

    to make using it even easier.   I felt the Control Box was located too far right of the actual working area.   So I  removed the Power Convertor,  Speed Controller and Forward/ Reverse Switch from the Control Box.   They were relocated on the Bead Roller

    in self.    These changes allowed me to control the Bead Roller Motor closer to the actual work area.

    Power Convertor moved to back of the Roller.

    The Speed Controller Panel was placed closer on the Roller for better visibility and speed knob and forward/reverse switch easier to operate.

    After these modifications, I also decided to add additional

    rollers so I would be able to do more sheet metal fabrication

    in the future.  Amazon had a set of Bead Rollers for $150 and

    ordered it.

  10. Motorizing my Bead Roller-

        

      I decided to put a Electric Motor on my Woodward Fabrication Bead Roller after I discovered that manual bead

    rolling requires another person to turn the crank.   It was impossible to turn the crank and guide the sheet metal into

    the bead roller at the same time.

        I will attempt to motorize my bead roller for under $100 so anybodycan afford to build one too.   The biggest expense

    would be the low speed but high torque motor.   Fortunately, I found a old Super Winch which was about 20 years old off of a Honda ATV.    It had a High Torque Low Speed Motor and it was Free.   On You Tube, people have used all sorts

    of stuff to power their bead roller.   Harbor Freight has ATV winches, 1/2 drills, electric pipe rethreaders,etc  All of them could provide thenecessary power.  Harbor Freight ATV winch can be gotten forabout $60-$70 for example.

    IMG_3339.JPG.ca894975a4585ecee0ef90f5760d55e1.JPG

     

       With my Super Winch, it was necessary to cut the cable spool off and shorten the spool about 2 1/2".  Then the

    shaft was reduced to 3/4" to match one half of the Flex Coupling.  The other half of the coupling was

    1" to match the bead roller shaft.   Amazon had a Flex Coupling 3/4 to 1 for $27.   A flat spot was created on the motor shaft for the allen screw to prevent it from spinning.   The winch body had to be shorten to compensate for the shortened shaft.   Sorry i don't have pics because my friend who has a lathe at his house did the machine work there.

        I ordered a 120AC to 12Vt DC 15amp Power Convertor from Amazon for $25.

    if your budget is tight, you can skip the Power Convertor and just use a Car Battery instead.

     

    A Variable Speed Controller,however is a necessity to control your work speed.   Amazon provided the Variable Speed Controller for $24.

    IMG_3159.JPG.ee31ca97ed22cd8163af82e92674168d.JPG

     

    The Controller had a Speed Control Knob, Forward and Reverse Switch and a Digital Display.

    The Display reads out in Percentage (1 to 100%) but looks neat anyway.

      Next was a Housing or a Box to put these electronic components to protect them against the elements.   I found  a right size plastic box to use and did a few mods to mount the

    components.   Used a Hot Knife and Dremel to cut Square Holes for the Display and Power Switch.

    At this time, I decided to add a Momentary Foot Switch in between the House Plug and the 

    Power Supply.   This switch would cut power off before entering a corner or stopping to change direction.  I got it from Surplus Center for $16.  I wired it so the switch could used for other motor devises like drill presses, bench grinders etc.

    Anthing that you might need your two hands to control the work piece.

  12. 5 star raising,

        The best way to solve your problem is to post pics of your hood -pics of hood rear gap, left and right hood side gap, hood front edge

    compared to both L and R headlight covers and hood height (frnt ,sides and back).   Leave the hood catch off till you fix hood alignment 

    first.   Always do one correction at a time then analysis the results.   Take the pics, it will make it easier to solve your problem.

                                                                                                                                                           Toolman

  13.   The Global Supply problems delayed delivery of my parts for modifying of my Bead Roller so I will go to LEATHER SEAT

    COVER REPLACEMENT-

       I ordered Two Leather Seat Covers from Interior Innovations for my car.   Cost was about $700 including freight.

    Be aware- Once you ordered from this company and received your Order Confirmation, do not expect to hear from them

    until you received your seat covers.   I tried to contact them by email and phone-no replies and no tracking number.  But

    I received the covers after about one months time.  On the upside, the Leather Seat Covers looked Good and Well Made

    but their Customer Service Suck!

       When I left off, the seats were without seat covers, the webbing was repaired and frame/seat back painted.

    Before starting, you have to decide if you want to save the original Steel Wire located in the Rolled over Edges of

    both seat and back covers.   I feel that the Steel Wire provides additional strength when stretching the seat covers on.

    The Replacement Covers have a small nylon rope instead.

    Initially you push the wire inward as you pull on the string with the other hand.

     IMG_3225.JPG.dd4eb5322b69736834db6aa70f5d81b6.JPG

     

    If you encounter difficulty in pulling the wire through,  attached the nylon string to a stationery object(like a vise) and

    slowly pull the wire through while keeping the seam straight as possible to prevents kinks.

    IMG_3236.JPG.dfeacfe081d2d9418208fca821c57001.JPG

     

    With the seat cover and foam facing the ground,  insert 3 Nylon Ties into the Seat Flap.

    IMG_3227.JPG.adb60ec03f8fe61542d06e8e41eb2d35.JPG Tape both ends together temporarily.   make the Ties wrap around the Steel Wire in the Flap.

     

    Place Foam Cushion over the cover.   Then "Fish Out" the Ties out.

    IMG_3228.JPG.8b99b726bec9c4d4cc4b0215f1fb70eb.JPG  As you found out, fishing the ties out was much easier because they were taped together. 

    Place the Lower Seat Frame on the Cushion.  Remove tape and tighten the Ties until the Flap contacts the Steel Wire.

    Use the Hog Ring Plier inside the cushion opening to install 3 Hog Rings to hold both the Flap Wire and Frame Steel Wire.   Ties can cut off at this point.

    IMG_E3230.JPG.a8f6fde17b18b8259a8bc85a5779b127.JPG

     

    If necessary, additional foam can be added the top of the Bottom cushion.

    IMG_3240.JPG.17c5c1d3869cc94d13bcfb33c03d5445.JPG

     

    Place the Lower Seat Cover over the Cushion Foam.  Work the foam under the cover be make fit properly.

     

    With a Cushion facing downward, the cover now needs to stretched over the seat frame.   You start at the Center

    of the Front of the Bottom seat first then work equally down both sides to the Back.   Cut a small slit in the Doubled

    UP Edge of the cover.   Stretch the over the Pointed Tabs (making sure the tabs are grabbing the steel wire).   A Wide

    Nose pliers or Vise Grip will make stretching easier.  Do not bend the tabs  completely over yet.

    IMG_3242.JPG.161f4a2312aa38de4a5e9586e489c01a.JPG

     

     

    If you having difficulty stretching the cover over the pointed tabs, a small screwdriver can be used as a pry bar to stretch the cover over the  pointed tabs to secure it.  Continue installing until you get to the bottom.   Then, you pull up the Back Flap and fasten it down.   Check the Top Side for any Low or High Spots.   You may have to stick your hand under the seat cover and move the foam around.  If you have vinyl Seat Covers, a Hot Air Gun might help removing wrinkles..

    IMG_3267.JPG.6613eb8d0c20ddbd07905729032fc97c.JPG

     

    When the Seat Cover seems tight enough, you can now tap down all of the Pointed Tabs  to add the Final Tightness.

     

    Seat Back Cover_

         The same installation procedure is used on the Seat Back Cover.   Replace the Steel Wire in the Top Flap and around the 

    Bottom of the cover before you start.   To Start, Turn the Back Cover "inside out" until the Top Flap is exposed.

    The top of the cover should resemble a cone shape.

    IMG_3250.JPG.ffa1981ebf17ffdbcd47ef584faf3e24.JPG

     

    Install 3 Plastic Ties in the Top Flap of the cover.   Place the cone portion of the cover cover over the top of

    the seat back.   Slowly push and pull the cover down the seat.  Add foam before sliding the cover that area.

    Stretch the cover over the Pointed Tabs till the right tightness is obtained.  After the Front Side of the cover

    is good then pull and stretch the Back side of the cover down.  After it is tight, then you can tap down the Pointed Tabs on the Bottom

    and call it Good.

       When installing the Seat Brackets, make sure to replace the Cleat Plastic Seat Cover Protectors.   They will protect

    the covers from unnecessary wear.   I replaced some them with copies made from  1/8" Rubber Sheets..

  14. Cooling System-

       A lot of time was spent looking a radiator for my LS 240z.  The biggest problem was the 28" space between the Front

    Core Support.   Most available LS radiators were about 30" wide.   But I found 67-69  V8 Camaro had narrow width of

    27".   So I called Champion Radiator for Pricing and Availablity.   He said because of the Pandemic affecting the supply

    channels, none was available and would not be for couple of months.   But fortunately, he asked me what kind of  radiator that I was looking for.   I told him 71 Datsun 240Z with LS swap.   Then he said they have Datsun Z radiator 

    for Chevy V8 swaps in stock.   The Radiator have 3 cores and can handle 500 HP.   Its dimensions are 27.25" with brackets and 

    core was 2.75 thick, 1.5" drivers side inlet and 1.5" passenger side outlet.   The Radiator cost with two 11" Spal electric

    fans and shroud was $389.  Shipping by US POSTALwas $130.  Totaling out at $519.

       IMG_3073.JPG.a133090a1af05894a49aa4d21ed5223e.JPG

     

    The Champion Radiator arrived less than a week later.   it was a Bolt On fit and even came with a 13lb radiator cap.

    The Test Fit showed the Radiator Cap cleared the Hood Bulge by !" clearance.   The Upper Radiator Tank was built

    with Forward Downward Angle which aided in  the clearance.

    IMG_E3139.JPG.6833978e30f93326731bb93e71c9c2f1.JPG

     

    Looking at the Grill Area, I decided to improve the Air Flow to the Radiator.  This would be accomplished by blocking off the area between the Core Support and the Front Air Dam.

    Using Three Pieces of .025 Aluminum Sheet Metal to create the Blocking Section.   First

    thing to do was to remove the White Paint on the Aluminum Sheet.   This was done by sanding

    with an Orbital Sander with 80 grit sand paper.

    IMG_E3090.JPG.37b77ec7494bc32b443d4f44760ed6ae.JPG

     

    A Paper Template were made to create the Three Blocking Sections.

    IMG_3084.JPG.d7e4de8b109a148d0aa63bb39823407f.JPG

     

    The Round Holes  were cut into the Two Outer Plates for the Grill Lower Mounting Brackets.

    At this point, I decided to attempt to construct the Front Engine Pan out Aluminum Sheet.  

    A Polished Aluminum Engine Pan would look Sharp in the engine compartment.

    After Sanding, the Guide Lines for the Bead Roller were drawn.

    IMG_E3122.JPG.fb12287d51fa9b9619cb5176a85a40ca.JPG

     

    using the Woodward Fab Bead Roller, the Reinforcing Beads were made to stiffen the pan.

    IMG_3130.JPG.d29ea859b1973ff2eecb17b1cffd2949.JPG

     

    After making a few beads, I discovered how difficult the beading process was to do by ones self.

    Trying to hold the metal straight and stretching over to turn the crank was next to impossible!!

    So decided to look into Motorizing the Bead roller.  These On-Line motor conversion run about $400 to $800.  I going to see if it is possible to do it for under $100.  Wish me Luck!!

     

     

     

     

     

     

  15. calZ,  In my case. There is no room to install a muffler on the Right Rear of the car.  See pics below-

    IMG_3065.JPG.e7fefff4c058151f11f9228dd28a6519.JPG Looking for Right Wheel Housing toward rear.

    I mounted a Holley Electric Fuel Pump in the a Custom Fuel Tank Sump.  Installed two 3/8 Nickel Copper Fuel Line

    and In-Line Fuel Filters running through the Trans Tunnel. 

     

     

     

     

     

     

     

     

     

     

     

     

     

     

  16. Mufflers and more Exhaust Work-

         I picked Thrush Turbo Muffler which consists of a Aluminiuzed Coated Steel Metal Body because of its small size and light weight.   But after Trial Fitting, it was little too long.  The original 240Z muffler space was made for only one muffler not two.

       Returned those mufflers and order Thrush Welded Turbo version which were 1" narrower and 1" shorter.  This installation was go down to a matter of inches of clearance.

    IMG_2939.JPG.6f33c524ce2f76104a76eee2487f428e.JPG

     

    The only disadvantage of these mufflers was there were constructed of 16 gauge metal so they were heavy.

    IMG_2906.JPG.d1d71cc0afb3fba54a02455444737de4.JPG

     

    They were Duct Taped together(to stimulate being welded together) and Test Fitted in.   It was a Tight Fit.

    Had to cut about 1" of the Lower Bottom Edge of Quarter Panel to gain Side Clearance.

     

    Supporting the Mufflers was another problem because of the tight space.  So I decided to construct a Single Hanging Muffler brackets.   So the mufflers were going to be welded together and supported by 1" steel rods located on centerline of both mufflers.  Also, because of the heavy weight of the mufflers , Two Rubber Mounts (or a total of four mounts) would be used.

    IMG_2931.JPG.a77c4b90b4e1201c7f32626a379106ab.JPG

     

    Mufflers were welded together with 1/4" piece of steel to provide a mount for the 1/2'" steel rod hangers.

    IMG_2912.JPG.4931bc293ed9e3ee4b3c7a440f524abe.JPG Steel Hangers welded on.

     

    The Rear Muffler 1/2" Rod Hanger was welded to the bottom of the Rear Bumper Mounting Bracket.

    IMG_2942.JPG.76ed5cc708ed0d371ce469da159a93dd.JPG  Note- There are two Rubber Mounts on the rod.

     

    This would be the Stationary Mount.   So when installing the Mufflers, you just insert the Upper Muffler 1/2" rod into the Rubber Mounts and push the Mufflers 0n.   Then the Wheel Housing Mount can be installed.

    IMG_2943.JPG.cb5157f1d8d63b8510493a298f0fca53.JPG

     

    This Wheel Housing Mount is attached to Two 5/16" Bolts welded to a strip of 1/8" plate on the Hatch Floor.

    The Outer Muffler Inlet Pipe still had to be modified to gain Tire Clearance.  The Inlet Pipe had to shortened as

    much as possible.

  17. More Exhaust Work-

     

       Pie Cutting- First, Creating a Paper Template for Reference  Points o the exhaust pipe.

    IMG_2955.JPG.29c7f99200248d35c39ec7e3c22b1df8.JPG

     

    This Diagram is for a 2 1/4" Exhaust pipe( just substitute your pipe size).   First, use your pipe size times

    Pie=3.14.  The result is the Pipe Circumference.   In this case, the result is about 7.06 inches.   So cut your 

    Template out Thin Cardboard or HD Paper to resemble a ruler.   Divide the Circumference by 2 to get the Half Way

    Point which is about 3..53 inches.   Wrap the Template about the pipe and the ends should meet together.

    Now , Draw a Straight Line down your pipe with Marker Pen. Mark this  Line #1. Use a Right Angle Protractor if necessary.  Wrap the Template around the pipe and transfer the Half Way Point to the pipe.   Draw a Straight Line Down the length of the pipe.    Mark this Line #2.

    Put your pipe into the Band Saw with Line #1 facing Straight up.   Adjust the Band saw to Desired Angle (usually 7 1/2, 15 or 30 Degrees).  Make the Cut.   Remember this First Cut will have  a Straight Edge on One Side.  Now,

    Rotate the Pipe to Line#2 (about 180 Degrees).   Push the pipe inward which will determine the tightness of the 

    Radius.   This will be the Thinnest  section of your Pie Cut( so keep it al least 1/4 inch wide or bigger).

    IMG_2787.JPG.89cbcbb56e5065e2b1c7e757ac583a16.JPG

     

    Do not forget to bevel both edges and sand the edges for the welding.  Also paint the inside of the area to be welded with Solar Flux with an acid brush.

    Tig Welding is Super expensive here.   My 20 -Argon Tank refill cost me $325.  If that is not Outrageous, I

    don 't what is!!!

    My X-Pipe cost about $40 from Amazon.

    IMG_2862.JPG.25a50b058004da3b87bdc63a39aef876.JPG

    A Jack Stand was used to support the x-Pipe while setting up.

    These V-0Clamps have Male and Female Connecting Edges which creates better alignment and sealing.

     

    Exhaust Pipe Hangers

        Amazon provided the Rubber Exhaust Hangers for $9 a pair.   These mounts were used because of their small size and strengthen.

     

       The Hangers themselves were constructed with 1/2" Mild Steel Round Rods.   The Rubber Mounts normally use 7/16" Rods but since my mufflers were going to be Heavy so the 1/2" Thicker Rods were used.

    The Exhaust Pipe of the Pipe Hangers were fabricated from 2 1/4" Stainless Exhaust Clamp Bands(from Amazon for $18.   These Clamps allow easy removal and installation.  Also, they

    can slide down the pipe to relocate the hanger if necessary.

    Next-Mufflers and More Exhaust Work

     

     

     

  18. My Post will be delayed because my Residence on the Eastern Portion of the Island is experiencing a Local

    Emergency-A  24 inch Water Main Break.   It has been Two Days since we have had running water!!   I

    have a go out Three Times a day to pickup 3 Galloins of Water from a Water Tanker.   This Water  is not for 

    Drinking but just for Flushing the Toilets!!  Tthe Water Company said  the Water Main should be fixed Today

    but we since Don't  Have Water Pressure yet.   The only shower that I take is Wiping myself with Water from

    a bottle of water onto a Wash Cloth!!!. Ughhh.

  19. Exhaust Pipe Construction

       I started off with Super Fast Racing 2 1/4" Stainless Steel DIY Custom Exhaust Pipe Kit from Amazon.   It was about $149.   The kit  consists of Two 45 degree, Two 45 degree, Two 90 degree bends and Two 48" straight

    sections of T304  Stainless Pipe.

    IMG_2593.JPG.067a76078f17932c63ac33704aa55c19.JPG

     

    I used a Electric Band Saw that can cut up to 4 3/4" .but you can use a !4" Chop Saw, a Sawzalll or even a 4 1/2 Right Angle Grinder with !/32" cutting disc.

    IMG_2654.JPG.04bf448734bdeab2052daf75e275671f.JPG  A Band Saw does make the job easier.

     

    A Craftsman 2/3 HP Belt Sander was utilized to straighten cut pipe edges.

    IMG_2655.JPG.698ce9e37a0c598fb311a971ca0f7963.JPG A 4' x 36" x 36 grit Ceramic Belt provided fast sanding.

     

    A Astro Pneumatic Small Air Belt Sander with 80 girt belt was useful in sanding tight areas,

    IMG_2616.JPG.8f732ca1cb50e79dabe8eaf3842b7d1c.JPG

     

    Since this project using a Tig Welder,  there was going to be a Very Steep Learning Cruve involved.  So I practiced, practiced and practiced.   Welding Thin Wall Stainless was like being thrown in  the Deep Side of the Pool while learning how to swim!    But I managed to get a hang of it but my Tig Welds were not anything to brag about.

    IMG_2603.JPG.23747f9c9dc05c6146b470e3acc5c94b.JPG  Practicing Butt Joint Welding

     

    When Tig Welding, Clearness is vital.   So you wipe down the area to be welded with Acetone to remove any contaminates ( from even brand new parts).  Then, you  should bevel both edges of your Butt Joints and sand the weld area.  At the same time get the Butt Joints as Tight as Possible.   Here is a Welding Tip:   Instead of Purging with Argon Gas the inside of the pipe, use Solar Flux type B.   It comes in a Pint can and cost about $49 on Amazon.  It is a dry powder that you mix with Alcohol to create a mud like paste.   You brush it on the inside of the pipe under the area to be welded.   When it dries, the paste will prevent "sugaring" which is oxygen contamination of bottom side of the weld.   Sugaring will create a tiny facture which can crack later especially something subject to constant vibration.  Another benefit is Argon Purging is very Expensive so wasting it is foolish.   Solar Flux, however, can not be used upside of a turbo because its residue might get suck in and damage the turbo blades.

    IMG_2835.JPG.b7e0f6a22f1da8ec063eb9f04aa368f0.JPG

     

    I also constructed a Tig Welding Jig to hold round exhaust pipe when welding.   The round pipe can be easily rotated when tig welding the butt joints.

    IMG_2618.JPG.d08a240248058e8e0bebe1197ca7666b.JPG

     

    To cut the U-Bends, I created a cutting board to mark the pipe for cutting.

    IMG_2647.JPG.0c05da245e327d4f0d62298b32a04363.JPG  Using the string and a marker pen to mark off angles.

     

    IMG_2648.JPG.d1b0278e57b3ab668222a5433364811b.JPG  Zip Ties on the pipe helps making lines around the pipes.

     

    After Cutting the  U Bend, you will notice that pipe sections are not perfectly round( more "egg shape".   This is because these so called Mandrel Bends are not True Mandrel Bends.   Just Cheap Versions.  However, True Mandrel Bends are available but cost a lot more.

    Next-More Exhaust Work

  20. New Exhaust System-

        After installing the Holley Flow Tech LS exhaust manifolds on my car, I discovered there was a Clearance Problem.

    The Driver Side -No Problems

    IMG_2551.JPG.7d7c975cee79deb919ddfd6489e786a5.JPG    Frame Rail

     

    However, the Passenger side Exhaust Manifold was too close to the Frame Rail.

    IMG_2626.JPG.0ba4bfce7c173ae1ffbc4c91c6a639c6.JPG 

     The Passenger Side was touching the Frame Rail so I tried to cut off about 3/8" off the bottom manifold ourside edge.

    IMG_2642.JPG.a47f3ee9ada65ced9d25849e28639199.JPG

    But ,it was still too close.  I considered shifting the motor to the left but that side didn't have the extra space.

    So the only alternative was to "Notch" the Frame Rail.

    This is one the possible Notch design.

    IMG_2643.JPG.1c410061ea8b115bd544f24c974b9e6e.JPG   This model was made using the same Frame Rail material.

     

    But no matter what, Notching would require the motor and transmission removal again!   This would be the Sixth Time the Motor/Trans had to be removed.   Nobody said engine swaps were Easy, right?

    IMG_2705.JPG.30682865318312cc86cedf7ed19d62d5.JPG   Out Again

     

    This is the my Drawing of the Frame Notch modification.

    IMG_2713.JPG.73da75ef61b730f66dd6224808eb6071.JPG

     

    Here is a pic of the Tools necessary for this job.

    A 4 1/2 Right Angle Grinder with Cut Off Wheel was used to slice the Top Edge of the Frame Rail.

    IMG_2702.JPG.e31376f61eb93ab91951d29623f06003.JPG

     

    Then a Oxygen Acetylene Torch heated the Notch area "Cherry Red".   Then a 5 pound Sledge Hammer pounded

    the area. to create a "Rounded Spot"

    The Upper Frame Rail were cut to match the cruve of the Notch.  Then 3/16" gap was then welded with a Mig Welder with Two Welding Passes.

    IMG_2707.JPG.84a9c8aae68e79c3d60d25485d041746.JPG

     

    The Notch and Weld was grinded and covered with EverCoat Polyurethane Seam Sealer.  The area was then painted with Polyurethane  White Paint.

    IMG_2722.JPG.d93d6ebabde78bdeb0f51806c4954fa8.JPG   Note-those holes were previously

    drilled there for future rustproofing access.  The rust proofing plugs will then be installed,

  21. DonH, Thanks for feedback on the Leather Seat Covers.   Good to know that Company makes Good Covers.

     

    Dash Board Installation-

       After receiving  the SEM Textured Black Dash Board Paint,  I repainted the Dash Board.   But while installing the dashboard,  I discovered that the my Aluminum Replacement Glove compartment had to be modified to fit.   The Compartment Top had to be Notched to clear 

    Dash board Ducts Hoses.

    IMG_2781.JPG.7cfd25ecdf3ddb279b03179bc7e71f28.JPG  Used the Brake to create the Notch

    for Glove Compartment.

     

    Cleco Pins were used to test fit the Notch on the Glove Compartment Box.

    For those of you who missed the Dash Board Restoration- Go back to Feb 4, 2019.   The Dash Board was in Eight Pieces after it fell off my work bench.

     

    Exhaust System Build-

         I decided to build my Exhaust System starting with Holley Flow Tech LS Cast Iron Exhaust Manifolds.   They have 2 1/4" outlets and  are Ceramic Coated.   Cast manifolds will

    eliminate some of the Heat and Sound in the engine compartment.   Ebay sells them for about $260.

     

    IMG_2592.JPG.97278d789e69aef1d7c3d9d0522523d9.JPG

     

      The Rest of the Exhaust System would be fabricated from this  Universal 2 1/4"  Stainless Steel DIY Kit from Ebay.   It costs about  $150.

     

    LS Exhaust Manifold Gasket Kit runs about $20 on Amazon

    IMG_E2597.JPG.540dc54ed2cd21091bd4ddacc6b75c46.JPG

     

    Building an Exhaust System for a 240z without a Exhaust Tubing Bender and a Vehicle Hoist

    will not be easy.   Especially making it out of Stainless Steel Tubing and the fact that I never 

    Tig Welded before.   Please be Patience with me!!

     

  22. Sorry for the delay in posting but couple of unforeseen problems came up.   I was planning to go over the installation of my Reconditioned Dash Board but could not find the SEM Products Textured Dash Board Spray Paint on the island.  Since Federal Express and UPS won't ship Pressurized Containers, my Spray Paint would have to come by Boat.   That trip would two to three weeks so I went to another item to restore.

     

    Front Bucket Seats Restore

        Both Left and Right Seats had lot of wear so probably would go Restoring them in Leather.   First  Step was to Disassembly to check the internal condition of the seats.

     

    IMG_2559.JPG.9082f761776e91e8e3473931b2a4d493.JPG Removing the seat coats just requires removal of the Hog Rings that hold the covers on.

     

    IMG_E2575.JPG.60e944a6fd35addfaf15ead74d5a683f.JPG Sand Blasting Seat Frame and Back

     

    They put a Thin Clear Plastic Sheeting over the Seat Foam to make it easier to "slip" the

    new Seat Cover over the Foam.  It can be replaced with any real Thin Plastic Sheeting(like

    the kind from Dry Cleaning Shops).

     IMG_E2571.JPG.a5b8ad7af4e2dcd1ef69f31080544177.JPG

     

     

    IMG_2562.JPG.8b4807ec816b4a52d1ddfb201391abc3.JPG

    Both Seats had Broken Seat Support Straps( located under the foam seat cushion).

     

    If you plan to repair the seats, you need to save the Metal Support Wires that hold the seat covers to the frame as they might not come with new seat covers.

    IMG_2565.JPG.ed8f7f6de9cddccbf67955acee57a599.JPG

     

    I used Webbed Belts from Ratcheting Cargo Straps to replace the Broken Straps.

    IMG_2577.JPG.3a4ccb2096bbe83b6d86aeee88669a70.JPG

    Loop the Cargo Straps around the Old Factory Strap Connectors .   Hot Glue is used between the Folds to provide

    additional strength.   A 1/4 Air Riveter is used to install the 1/4 rivet to secure the webbing tightly too.  Solid Aluminum Rivets can be utilized.

    Pricing both Vinyl and Leather Seat Covers on Amazon and Ebay came out to $400+ for Vinyl and about $700

    for Leather Seat Covers.   I decided to wait and possibly look for Junk Yard or Craigslist for   a Pair of fBucket Seats.

    The Heater Box is normally attached to the Cowl Inlet Vent with Four Small Screws.   I decided to mount the Heater Box by a different  method.

    IMG_2440.JPG.e8018719cf7ffada489e4ab49d4284e6.JPG  Instead of the screws, I made a Right Angle

    Bracket that would support the Heater Box from the Top  of the Cowl Cold Air Inlet.  Two Threaded 10-32 Rods would be suspended from that bracket.  The rods would go through another bracket

    attached to the Heater Box Housing.   Two nuts on the rods were be tigntened till they supported the Heater Box to the Cowl Inlet.  This similar hanging mount was utilized on 64 to 70 Ford Mustangs Heater Boxes.

    Note- To tighten the two Mounting Rod Nuts, the Duct Door made be in "Open" Position to access the nuts.

     

    Both Heater and Evaporator Cores were  cleaned with AC Condensor and Evaporator cleaner.  Cleaning removes grim and mildew from the Aluminum Fins.

  24. Twisted46, Go to my Post-Heavy Duty Frame Rails Feb 13.2021 to see what I did to modify the Diorty Dingo Mounts.   I wanted to set back mm LS3 close to the Firewall too.

    JTR Mounts puts the LS mounts more forward than Dirty Dingo too if you don't want to fabricate a new motor plate.   Check the related photos to see if the clearance

    is sufficient for your purpose.   One disadvantage of the forward mount position is you can not locate an AC compressor on lower front side of the motor.   You probably

    will have to mount the compressor high on the Right motor side(near valve cover).    The other option is reinforce the frame rail and locate the LS motor mounts directly

    on the LS block mounts.   That position would allow for the lower AC Compressor mounting but might interfere if you are running full length headers.   Engine Swapping is

    a "Give and Take"  Proposition.
