Heavy Duty frame rails and connectors

Recommended Posts

 Back in 1971, this 71 240Z was my First and Only Car.   It was a Total Wreck- the owner ran it into a large Bulldozer parked on the side of the road.

My father owned a automotive body shop which had 5 frame machines.   We fixed often repaired totaled cars.   So we put it on the frame machine

and pulled it straight with multiple 10 ton hydraulic rams.   Then the damaged pieces were replaced with OEM parts.   I drove the car "stock" for

about a year but decided it needed more power.   I first checked into modifying the Nissan 6 cylinder motor by Weber carbs, turbocharging and 5 speed racing transmission).   But those options were way too expensive.   Being a Chevy drag racer, putting a Chevy 327 motor with Turbo 400 transmission seemed like a easy answer.  So after gathering all of the needed parts, I pulled the old six engine out and put the 327 in.   I had the car running in a week time because I  had to use vacation time to do the conversion.   At a later date, I put a more  powerful 350 and T-5 five speed trans and put metal flares on.   In 1988, I bought my second car 88 Chevrolet Astro Van for business.   My 240z was basically sitting in the garage

since that time.   So I owe it to spent some time restoring it as the best that I can do.   I hope this story explains my restoration.

    Back to the restoration:   I put the  Wheel Fitment Tool on the car to check the wheel alignment out.  But first, had to remove the strut coil spring as it won't allow the body to drop as there was no engine weight and accessories.

Put the Wheel Fitment Tool to test it out.

Wooden blocks were placed under the lower control arm to adjust ride height.  The car is still on a dolly which lifts the vehicle about 1" higher than a stock Z.

IMG_6573.thumb.JPG.952aa87e251f377a466c85d6c8da1c21.JPG Using a Tool Aid Wheel Alignment gauge to check Camber readings.


A carpenters square shoed the hub to be close to zero so I set the gauge to zero degrees,

IMG_6572.thumb.JPG.3dfc45d8828fe3a8d0f1eba9939a5456.JPGAfter checking the Square with the ground, I reversed it to better demonstrate camber.


By tilting the straight edge top outward(away from the car) to stimulate Positive Camber.

To stimulate Negative  Camber, I titled the top of the straight edge inward( toward the engine compartment).

I think there was a misunderstanding about what I trying to accomplish.   In my particular case, I am trying to eliminate as much Negative Camber that I can.   Lowering the car with shorter springs, lower ride height, extra wide wheels,etc will create a lot of Negative Camber.   Shortening the lower control arms, upper camber plates, modified spindles,etc maybe utilized to provide Positive Camber to achieve alignment.  My car will be basically a Street Car and not a Race Car requiring 3 degrees Negative Camber.   Now, you can even change front and rear crossmembers to get the alignment that you want.

  The wheel fitment tool was designed to  go to even  a 12" wide tire.

IMG_6661.thumb.JPG.f62bdad90cfe34df6440593e62d679ba.JPG  As I only had a 8" wide tire, one has to imagine the other 4" extending inside the fender.



First, Zeroing the Camber gauge



IMG_6598.thumb.JPG.9a2705c6c521294d0bc94cfcbaf31704.JPG  Camber gauge zeroed in.

Then, holding the straight edge with camber gauge against the outside of the tire.

IMG_6625.thumb.JPG.1274c91a589249b402f8b2524f4ecf0a.JPG  The Camber reading is 1 1/4 degrees Pos  

  IMG_6646.thumb.JPG.966a41dcac63caac0cd9c905833d08ca.JPG  This wheel/tire combination would require a 3" fender flare.


  In this case, the wheel had a 2" Negative offset-the wheel center was 2" inward of center of the wheel.



The 245 X 18 X 8  offset wheel/tire combination looks like this from the front view.  A mild street look.





Do not forget that the ride height is still not correct.   The present ride height is about 3" to 4" higher than what it will be with the new coil over suspension.   Lowering the vehicle will create negative camber and bring the camber to closer to a zero reading.   Also, keep in mind, these are only simulations and I am going to larger tires and wheels.

Next thing to work on was the rear control arms.  First, I cleaned them up to remove any dirt and grease.   Then, they could be sandblasted with 

#80 grit media.   Next, removing their inner bushings was next.   Using a air saw, I cut two parallel cuts in the inner  metal bushing.

IMG_6729.thumb.JPG.0a407dcb311e8d4372010dbec53e418b.JPG If you don't have a air saw, you can use a hack saw. But you have to take the blade off

the saw then stick in the bushing then reassemble the saw.   Saw two parallel cuts through the inner metal bushing.   Remove it and use a

air chisel to push the inner bushing out.



Try to get the bushing to collapse and fold over.    If not, use a torch to burn away the rubber portion of the bushing.

IMG_6730.thumb.JPG.fa068fc564e7c855b0e05b270c8cafaf.JPG  Besides the burning rubber, avoid being burned by hot rubber pieces.


Remove all the rubber from the bushing with a wire brush.



Now, use a Sawzall to cut two parallel cuts in the outer part of the bushing.   Be careful not to damage the control arm while doing this task.

Use a air chisel to collapse and push the bushing out of the arm.

IMG_6770.thumb.JPG.dfcaf8f0428edeb0f4ae67323dcc18c4.JPG The removed outer bushing should resemble something like this.


If the control arm was damaged while removing the bushings,  you can repair it before installing the new bushings.



The control arms ready for powder coating.



Control arm in my powder coating oven.



Now, I have to wait till my control arm bushings to arrive so I can press them in.

When the Postman brought a large box for me, I ripped it open immediately-it was my CRX Racing Coil Over Suspension kit.

814947767_IMG_6687(1).thumb.JPG.722b97e2beb39fda8391da6da3ce733e.JPGShorter ones were for the Front and Longer ones for the Rear.

The cost was $850 plus $150 for freight.  CRX has installation instructions at their online site.

Installation is simple.  You cut about 2" to 2 1/4" from the bottom of the strut tube then weld the external sleeve to the strut base.

IMG_6688.thumb.JPG.1337123b92762523f517b2f690ff918f.JPGBottom sleeve and coil over strut section.

I measured the length of the coil spring to record the spring preload.   The lower threaded section allows you set the ride height that you want.

298589482_IMG_6694(1).thumb.JPG.fa23f60cccb4924ce201583e40694f99.JPG  Struts were disassembled and sandblasted to prep for welding.


After taping the cutting line, I started the cut by using a hack saw.



1135889332_IMG_6698(1).thumb.JPG.0dfea442c01461835dfa72d07d8b20de.JPG  Then a SAWALL was used to finish the strut sectioning.


IMG_6720.thumb.JPG.b542225bdf336ad093187b50b6fa585c.JPG  Sectioning completed




The Front Spindles had a casting bump between the tube and spindle casting.  I sawed a V cut in it to provide more welding space.

The Rear Spindles don't have any casting lump.

IMG_6714.thumb.JPG.09c0049db7a49f83606f21f93aeb1d97.JPG Welded up spindle


All four struts were sent out for powder coating as it is too bulky for my small oven to heat up.


All four Spindle Backing Plates needed cleanup to be powder coated.

                                   Front Backing Plates  after Powder Coating



Rear backing plates powder coated



Hopefully, the Powder Coating guys won't take too long on the struts so I can put the suspension back together.

Trying to decide whether to use Bedlinder(Raptor, etc).  Anybody have any comments about Bedliners?

PROJECT TIP:   I am posting this tip as it may be very helpful to a lot of people.  RESCUE BIT is a high speed cutting bit that will cut through broken taps, extractors just about anything.  Check the video out at https://www.youtube.com/watch?v=FkIH7DhQJzA

In my case, I was tapping out the bolt holes of my struts.   Of course,  while tapping the last bolt hole, the 6mm x 1.0 tap broke.

IMG_6739.thumb.JPG.7774a58b43e3ecfa28ad7c08aa04ac0b.JPG Pic of the Broken tap


This is a picture of a 1/8" RESCUE BIT with cutting edge on both sides.   The 1/8" version must be used with a 1/8" adaptor to use it

in a 1/4" die grinder.                                                                                                                                                                                                                                  IMG_6740.thumb.JPG.794a3abee038d602b5daf9202dc03739.JPG Pic of 1/8 to 1/4" adaptor.    Rescue Bits also use to have 1/4" burrs (single and double cut version) too.    Now the Rescue Bits can be found

on Amazon and Ebay but only here and there.   I don 't think the company still exists.   I do keep one around for emergencies like this one.

IMG_6745.thumb.JPG.6d35c46152ed3db448cffe0a7b99a927.JPGAfter drilling a hole in the center of the tap.   I use a small sharp punch to collapse the walls of the tap inward.


Here is one the larger pieces of the tap that was removed from the hole.



After removing all remains of the tap,  I carefully tapped the hole with a new 6 x 1.0mm tap.




Success-bolt was threaded in!!     It is important to  carefully follow the instructions that come with the Rescue Bit.  Also. the die grinder

must be capable of 25,000 RPM.   High speed and the bit design is what allows the Rescue Bit to do what other bits can not do.    I  hope some of you find this tip helpful.


IMG_6738.JPG  Rescue Bits costs about $60 online.

    The door hinges for both Left and Right sides were top coated with Polyurethane paint.   



Shop Tip- Removing and Installing a 240Z hood by yourself

Place a Plywood on top of the Left and Right fenders.   Put hood in the closed position.

IMG_0014.thumb.JPG.bb61750003ec677a4502cee3b6cb805e.JPG Put card board or padded mat under plywood to prevent scratching the paint.


Raise hood to open position.     Loosen all four hood bolts but do not remove.

IMG_0016.thumb.JPG.c0fd84a4f8d70e69e7d311d11ac95376.JPG  Remove both hood front bolts.

Now tilt the rear of the hood downward till the hood contacts the plywood.   Then remove the rear hood bolts as the hinge and plywood will support the weight of the hood.   The hood can be lifted off from either side of the car.   Hood installation will be the reverse procedure.


The next thing to do to spraying Raptor Liner in the fender and wheel wells.

IMG_0025.thumb.JPG.6ec744091eb2489ce2989b3441005020.JPG   This Raptor liner was the 2 bottle kit with Liner, hardener and color toner..

This kit costs about $100 including freight on Ebay.


Masking the hood to prevent overspray going all over the place.



The interior sides of the hood and fenders were sanded with 150 grit sand paper then wipe down with paint prep solution.

IMG_0039.thumb.JPG.decb65819453bc946faeadb673cce226.JPG  Note- Liner even covers patch area.


Left side Wheel Well Housing




The Raptor Liner can be applied by hand roller or sprayed.   A Schutz gun is most commonly used to apply the liner.   HLVP spray gun with 2.0 nozzle can be used if liner is reduced by 20%.  This method would provide a smoother finish( not as rough}.   After one hour, the liner is dry to touch.  It, however. takes a full week to completely cure.   I used only one bottle of

Raptor Liner so far.   The remaining bottle will be used for the rear wheel housing after I finish flare modifications.

I just got back from Tokyo.  I managed to go Japan's Largest Automotive Store in Japan Autobacs Shinome located near Tokyo Bay.   The garage is on the bottom of this three level store.   The main store is on the Second floor and has a coffee shop there.  the third floor is the high performance stuff.



Snap On tools on display in glass cases.  Snap On Tools tools sell for twice the US price.

Snap Tools on display.

    On the third floor, the high performance parts and accessories were on display.  They had the latest GPS., stereo ,DVD, and LED lights.

And, of coarse, the garage downstairs could install whatever you purchase.

There was a rear driving simulator that anyone could try for a price.  It had loud speakers 3 TV screens and air shocks to give the real.feeling of a race car.0E6DF1BB-6A4C-46F4-810E-9387E4A8D5C5.thumb.jpeg.65ee8c404f4dcbf431e06417246e4ac3.jpeg


         I think the price was $50 for 30 minutes.    Unfortunately, I found about the simulator too later as I had to get back to Shinjuku before the afternoon rush on the trains.   Passengers are really packed like sardines during rush hour!!!!!

Then paining Polyurethane Primer Sealer on top of that bodywork.



Not to forget the inside of the front fenders,  the sealing of them was next thing to do.

The wheel well deflector plate stripped and painted.   I decided to use rubber weather stripping.  I found 3M "D" shaped weather stripping on

Ebay for $13 for 8 feet.

Previously I had planned to use Dynamat or similar foil type of insulation for the floor and roof.   However, I decided to use Lizard Skin Ceramic Insulation paint.   It can lower the interior temperature 20 to 30 degrees. One gallon costs $100 on Amazon.  They also sell sound insulation paint(costs $100 gal) but it must be applied first(before heat insulation).



Had planned to spray it on with a Schulz under coating gun but the coating was too thick for the gun.  So I used rollers and a brush to

apply it.   A cordless drill was utilized to stir the paint.   Use low speed and in Reverse so the particles are not damaged while mixing.

Application was done in two .020 coats allowing the first coat to dry to the touch.   Curing will take possible a week to completely cure  depending on weather conditions.




All holes must be masked off to prevent over spray.

IMG_0169.thumb.JPG.8ece892e87d6afac1726db6984ec0ecf.JPG  Areas to be painted are scuff sanded and all threaded holes are plugged.


IMG_0195.thumb.JPG.2e8eb62aa503e87f386d271ef6dca81a.JPG After painting


Ceramic Coating was not difficult to apply.   Cleanup should be done quickly as the insulation dries relatively fast.

After the Ceramic Insulation is cured, I will probably top coat it with Polyurethane White Single Stage Paint for added protection.

Lizardskin is good stuff! It does work on sound and heat insulation. Also VERY lightweight. The urethane is a good idea. I used a black single stage industrial urethane on my JK project over the Lizardskin.


Your project is really coming along nicely.

That was the price that they quoted me.   The major problems with this portable spray booth is it is made out plastic and it does not 

have a fire suppression system.   Most local fire departments would not allow such spray booths to be used.   If some one was caught inside in one that caught fire, they would be trapped under a collapsing structure.

Ebay has a lot of portable China Spray booths that run from $1000 to $2000.  Most are a little more than inflatable bounce things.

The one at the SEMA is manufactured in Texas by Mobile Environmental Solutions.   Single booth 23' x15' was $9995.00 and twin booth 23' x 48' was $19995.   They seem to be made of material similar to those auto paint shop curtains that divide up shop areas.   According to them, the booth is made of materials that pass NFPA (National Fire Protection Association)701 test methods 1 &2.  TV's Garage Squad show  is shown using their booths.   But I would check with your local fire department 

first before purchasing one.

Finishing under the front fenders

    Decided to make the upper front fender splash deflectors.  Bought garage door bottom edge weather stripping from Home Depot for $12.

IMG_0212.thumb.JPG.27f006a552f7272b35bb8b2c37be7451.JPG Used a knife to remove both vertical edges to end up with a flat rubber strip.


I bent strips of 2" wide sheet metal to create a "S" shaped clip to hold the deflector on the fender support.   As I was making the clips, I could adjust the holding tension of the clips by adjusting their gaps.



Fender upper side deflector installed.



IMG_0215.thumb.JPG.0dc705d5997f5d0834c203c24de1d1db.JPG Closeup view of clips

Note- The clips edges are bent up slightly to prevent sharp edge from cutting the rubber deflector.


  I ordered a set of Dimple Dies consisting of sizes from 1/2", 5/8", 3/4" and 1".   Using these dies make flat sheet metal a lot stronger and looks "real cool" too.   The 240z uses this type of metal forming on its inside rocker panels ,strut supports,etc.



First, thing to do, is drill a pilot hole in the sheet metal.  In this case,  the 1/2" Dimple die requires 5/16" pilot hole.



Next,  assemble the Cutter blade and bottom die with the 10MM head bolt.

IMG_0442.thumb.JPG.f24ea27b1af69e6e5b5b21372b2b315d.JPG  As you tighten the bolt, the Cutter blade also turns and cuts a hole into the sheet metal.

Continue to tighten the bolt until the Cutter cuts through the sheet metal.


Once, the 1/2" hole is made, you reassemble the forming die with the bottom die.

IMG_0443.thumb.JPG.91b6453e1ff09859f4d46b74cea3f7f7.JPG Tighten down the Forming Die until it

is flush with the surface of the sheet metal.


Disassemble the tool and inspect the Dimple Form.  If it's not formed enough, reassemble the die and tighten it down more.

IMG_0447.thumb.JPG.c16e414640ff9fd0a4b64bed1c00361b.JPG   Side View of the finished !/2" Dimple.


I will probably use the Dimple Dies to create some support brackets in the interior and maybe construct a Triangular Engine Compartment Support with them.

  A problem occurred with the weather stripping that was glued to the rear inner fender deflectors.   The adhesive was strong enough to hold the

weather stripping on.   The solution was to use "T" type  weather stripping clips( from Chysler) to do the job.

  Got them from Ebay.


3/16" holes were drilled into the deflector plate.



A small scissors was used to create a "Diamond" shaped hole in the weather stripping above the corresponding hole.


Twist the "T" clips into the hole In the weather stripping.



Push the "T" clip completely into the mounting hole.



Pic of the "T" clip fully installed.



The Lower fender flap was installed using two "Christmas Tree" type retainers(from Ebay).

The retainers replace screws which tend to fall out.

The original door glass molding was in terribly shape.



First thing to do was removing the old weather stripping.  The old weather stripping is attached using staples.   The best way to remove the molding is to twist the weather stripping with pliers to continue to "roll up" the weather stripping.



If the stainless has scratches or small dents, repair them first.  Then, sand with 400 grit sand paper then slowly progress to 1000 grit.   Then, use a cloth buffing wheel prepared with Stainless Steel Polishing Rouge to get it to look like new.



I tried using pop rivets to hold the weather stripping on the molding but the rivet head protruded too far inward.



Instead, 3M spray adhesive was applied to under the weather tripping and on to the molding surface.

After waiting 30 minute for adhesive to dry, the weather stripping was installed on the molding.
