    Sorry for Not Posting for a while.   After my last post on Jan 30,  I went my Orthopedic Surgeon to check on

my Sore Left Knee.   He previously did a Partial Knee Replacement on my Right Knee about 6 years ago.  At that time,  my Left Knee was not too bad but I had pain occasionally.  After the 2022 Sema Show, my knee got real bad to the point that I could hardly walk at the end of the day.   So I made an appointment to have my Left Knee checked out.   No surprises, the X Rays showed Bone to Bone Contact causing the pain.   So I wanted the surgery as soon as possible.    But I did not expect that there would be an opening for my surgery in only 2 weeks.  So on Feb 15 , I had a Total Knee Replacement Surgery which consists of installlation of a Titanium Joint inserted into my leg.   I went home the same day but I knew that the Physical Therapy would be Painful and take Months too.

As the new AC Compressor Location changed the Drive Belt Arrangement for the Alternator so

new mounts had to be constructed.

Because of the Evaporator Hoses, the Glove Compartment Box had to shortened in Depth by 2"'



So now, the Holley ECU Box was mounted in the Lower Shelve.   This postion is better for view the ECU LED Trouble Lights.  The Upper Shelve would  be the New Glove Box although smaller.


The Glove Compartment Door Hinges were slotted to provide additional adjustment.




Next- More Modifications to AC Vents ,etc.

Reapairing Right Side Dashboard Ac Vent Hose-

   The Right AC Vent  2"Hose was broken off from the Duct Vent.   So a method to reconnect that hose would have

to be found.    I diecided to use a 3' piece of  2" radiator to"splint' the Vent Hose to the plastic Vent Housing.




 Used the Hot Glue Gun to adhere the Spint to the Vent Housing.

The Finished Repair if the AC Vent Hose and Duct


I had to fabricate a Micro Phillips Screwdriver to remove the Three Phillips Heas Screws to Chrome Duct Vent.



This Micro Phillips Screwdriver also was used in other 'tight spaces" where normal phillips screwdrivers would not fit.


Modifying the Dashboard Center Vent-

   The Original Center Console Vent only had a small piece of foam around the vent tube leading to the Blower Box.

I decided to construct a sheet metal Tube that provide a tighter seal to Outlet Vent.



Making Template for the Vent Connector


Bending the sheet metal with a 5/8" deep socket to match the template shape.

Replacement of Heater/AC Blower Fan-


     Finding a Replacement Blower Fan especially with the similar mounting arrangement and size was not easy.   The

closest one that found was  one from a Kai Sportage for $99. This was a brand new one and a rebuilt one.   The blower shaft was the same size as the original Datsun.   Their Fan was slightly larger (about 1/4"}but made of black plastic..




Its speed was a little faster so hopefully it provide more air flow.


Replacement Electrical Connector Plugs-


     Alot of my original Datsun Plastic White Electricl Connector Plugs were pretty brittle.    



   So I found these Replacements on Ebay.

   IMG_4371.JPG.5d8843996a78ced6aa510e558446825e.JPG   2.3 connector and terminals


        Ebay also had 6.3 connectors and terminals but I could not find its pic.


Repairing Interior Vents-

    These vents draw air from the two air tube built into both top sides of the engine compartment.   Basically the vents function at high speeds (above 40mph}.   Some people forget to close them when running their Air Conditioning and wonder why the Air Conditioning is not cooling the vehicle.

    Replacing Foam gaskets on the Vents.


Used Contact Cement to Glue the form the Ducts.

     i replaced my Original Factory Wiper Motor with one from a 1992 Honda Civic.   Amazon had a Cardone New Wiper

Motor #85-1423 for $105.   This particular wiper motor has "Parking Return Feature" which returns the wiper blades to return in the Parking postion when Shut off.   The original Factory does not have this feature so the Driver has to accomplish this task manually.



This Honda Wiper Motor has the same mounting bolt pattern so the installation is easy.   Also the  Motor rotation is the same.    The Datsun Wiper Mounting Plate has to "notched" for the Honda Wiper Motor Clearance.   The Honda Motor

was similar Mounting  Slot for the Datsun Wiper Arm and bolts right up.

   A Hot Glue Gun was used to glue down the Hoda wiring to prevent possible  wiring problems.



The most difficult portion of this installation is the Electrical Wiring of this swap.   A Water Proof Relay was utilized as the

Wiper Motor is located in the Cowl Section of the vehicle.   I used -irhassody 40.30 Amp 12vt Waterproof 5 pin HD relay $11 from Amazon.

       This is my wiring diagram for this Honda Wiper Motor Swap.   Double check the wiring colors as I found some wiper motors has different wiring colors.




Honda Wiper Motor installed.

Yellow 240z


Any more info on these cars? Do you know who built them? I've googled and can't find anything on the green car. 


Edit: I've now found that it was at the Toyo Tires Treadpass Booth, and some additional photos of the car, but still no sign of who built it. It has Apex's Track Attack Kit on it, can't be too many of those around.

Replacing Precision Door Weather Stripping


   I found out that the Precision Door Weather Stripping was not doing its job.   It seemed too hard and not sealing the

interior from air leakage.   Even after adjusting the Upper Chrome Window Channel  inward to the Maximum Adjustment.

So I decide to look for a Weather Stripping Replacement.   I found an Univerisal Automotive  Door Weather Stripping gasket on Amazon.





Two of these Univerisal Weather Stripping Gasket are needed for both sides(Left and Right.   This Gasket was soft but large to handle large door gaps.   This style of weather stripping is used on most late model vehicles.   The only problem was the 240z has a Right Angle-90) degree on the Upper Rear Corner of the door opening.   The gasket was made for Slow Sweeping Corners.  So some fabrication of the weather stripping would be necessary;

Pic of Precision Corner Section which made by Vulcanizing rubber to create the Right Angle section.

IMG_5779.JPG.e4c6465d0e4712805df981cd90fcda38.JPGPrecision Door Weather Stripping gasket


    First, A DoorTemplate had to be created to make the Right Angle Corner Piece which will hold both ends of Weather Stripping.  This template will be used only for the constrution for the Right Angle Rubber Weather Stripping  portion.    A Corner Template made of 22 gauge sheet metal will be made to hold the two parts of the Corner Weather Stripping.   This thin sheet metal right angle piece will inserted into in the slots of the each end of weather stripping.  After Trial Fitting, this piece will glued with E6000 to fasten both ends of weather stripping forming the Right Angle or Corner Piece.

The Connector Template inserted into both  Weather stripping ends to Corner piece.



A Foam Square was cut out of 1/2" Soft Foam to fill the Corner Gap between the Two Weather Stripping Edges.  Note, this Right Angle Connecting piece  will become a permanent part of

the weather stripping after glued all together(connector piece, Foam Filler and both Edges of 

Weather Stripping} with E6000 adhesive.

over to create the opposite( Left) Door Template.

   The Best Rubber Adhesive that I found is E6000.  It is made by the same manufacturer makes

Shoe Goop.   It can be found on Amazon.    If you ran a bead of E6000 on piece of wax paper and let dry hard.   Then, peel it off the wax paper and you can stretch it 3 times its original size!!   There are two versions of E6000 -low viscosity and high viscosity.   It depends if you want the glue to fill in gaps or stay on the surface.

Note-a Right Angle Corner Bottom Piece was made from 1/16" rubber sheet which is glued to lower side of the Right Angle Connecting piece to provide a Bottom Sealing Surface.

Note-Foam Gap Piece installed.    E6000 is used to attach both weatherstripping edges to the Right Angle Connector and later gaps and edges will be filled with E6000 to prevent water intrusion.

I have not Road Tested the car to check for Air Leakage or Water Leakage yet.   Will let you

know the results of both tests when they are completed.

  i will discuss my Interior Modifcations created to add to the "Race Car" Imagine of 240Z Restro Mod.


Using Dimple Dies -

    Dimple Dies are used regularly in Race Cars to strengthen and at same time lighten vehicle weight.   Dimple Die tools are basically a Male and Female Round Hole Dies.   In the center, a Bolt is used to squeeze the sheet metal into a Reinforced  Round Hole.




Completed Dimple Die Panel



To create Upper Strut Tower Covers, A Paper Template was made First.



Strut Tower Brace  Covers  with a Polished Aluminum Rear Deck Plate



Rear Hatch Area also Large polished Aluminum Pan was added.




Another view of the Hatch Area




Interior Mouldings

Front Passenger Side Interior Moulding



Front Driver Side Aluminum Moulding



Lower Interior Rocker Panel Covers




Dimple Die Panel installed on Right Rear Quarter Panel



Aluminum Door Panels

 To install Aluminum Door Panels on a 240Z took more work as the interior side of the doors are not flat as most cars are.   They were constructed this way because of the confined inteirior area.


Trial Fitting of the Non Polished Aluminum Door Panels



This Test Determined that Spacers are needed because of the "uneven interior door surface'.    A Straight Ruler.   It shows that  3/4" spacers are required to attach the Door Pull Handles'



Note-Three Black Round Plastic 3" Spacers glued to the Door Skin with JB Weld.


The Other Problem is the Window Crank Handles is be extended by about 1/2" longer for clearance to operate.

A Extra Window Crank Handle must be use to cut the Spline End off to extend the shaft.   A Hole Saw is used to remove the shaft off the crank..



The  1/2"Cutoff Section is attached to the Original Crank Handle with JB Weld Adhesive.  This will allowe the Window Crank Handle to "clear" the Door Panel.

     Also, Other Modification that must be made to the Door Release Mechanism.to function properly.

     First, the Aluminum Panel must cut out to mount the Door Release Mechanism.


A Dremel Tool was used to perform this task.


Also, the Door Release Mechanism itself must be"Tilted upright" in it mounting position.    This is accomplished by fabricating Triangle shaped wood blocks under the bracket.


Oak Blocks was used for its strength ,avaiabllity. and ease to fabricate.

Two Longer 6mm x1.0  bolts are necessary due the Wooden Blocks.



Door Release Mechanism installed


Window Crank Modification

Using  a Hole Saw, a section of an extra Window Crank was removed.  This section

was filed down so the core portions would match for sectioning.



Window Crank Handle Extension joined using JB Weld 


 With this 1/2" Extension, the Window Crank Handle has enough clearance to operate.


Aluminum Door Panel now Completed-




Drivers side Door Panel



Fastners Used


All of the Dimple Die Alumunium Covers were fastened using Rivet Nuts and Small Machine Screws

(4MM x o.7 ). The only exception were The Upper Interior Aluminum Covers were fastened with 1/4"log Phillips Screws.


Radiator Support TopCover

I also added a Aluminum Dimple Plate to hold  a 1/4"x 4" wide Rubber Strip which seals the Hood and Radiator Support Area.  This Seal directs more air through the radiator.   Right now, the Water Temperature runs 193 degrees and up to 200 degrees with AC running.



Hatch Interior Cover

  A Polished Aluminum Flat Panel was attached to the bottom side of the Hatch.  It was attached with Plastic fastners.

Upgrading Interior Rear View Mirror-


    The Original Factory Interior Rear View Mirror has Blindspots due the Quarter Panel Pillars.

So I decided to upgrade it with a Multiple Rear View Mirror.   Race Cars use them to see better 

when passing other cars.

    Amazon had this one that was for Golf Carts that was 36" long.   Usually they had 24" rear view mirrors for cars but I felt the longer the better.  Plus , it was only $25 anyway.



This is a pic of the Rear View Mirror upon opening package.



  I decided to.make my own mounting brackets using the original rear view mirror mounting holes.

First,  Paper Templates were made using existing mounting holes as a guide.



Brackets are first created out of aluminum sheet metal making the shape easier.

Then, after the basic shape was established, Brackets were made from 16 gauge sheet metal.  The 16 gauge sheet provides the stiffness to support the weigh of the Mirror.



With the Brackets mounted and tight, their shape was acheived by slowly bending and twisted them to fit the mirror properly.  The Tilt Adjusting Knob was installed with a Small Rubber Gasket between the mirror and knob to provide additional tightness.


The  New Rear View Mirror was installed using the original mounting holes.




Close Up View-of Right Side view with the New Mirror


The Viewing Test was successful ( the Girl was visible in both Rear View Mirrors).
