Thanks for Repairing my PassWord Problem. Is there anything that I need to do prevent this problem from occurring again? Toolman

Sorry for the delayed reply. Was having difficulty with my Password and trouble posting. Thanks Administration for correcting problem. Disc brake and Hand Brake Installation- First, Important Notice-The Invinclble Extreme 8.8 Differential Conversion Kit requires the use of 2015 to 2024 Mustang GT Rear Disc Brake system. All related Suspension Parts were created to work with these parts. Check carefully if any alternate brake parts are used for fit and function. Otherwise, Different Parts may require Modification at some level. I utilized NAPA Replacements Brake Parts (Calipers, Rotors and Upgraded Pads) for 2019 Mustang GT I painted the Calipers and Mounts with Polyurethane Bright Red to improve their appearance, Stainless Steel Brake Lines(from Amazon) were used. Brake Line Adaptors from EBAY connected the Male OEM fittings to the Stainless Lines. Brake Line Adaptor installed with OEM Clip to Stainless Steel Brake Line Hand Brake Modifications- The Hand Brake required a little more fabrication to function properly. I found these adaptors on Ebay although they were not designed for this particular job. The Above Two Parts were used together to adapt the OEM Hand Brake cable to the Mustang Caliper Hand Brake Cable Mount. The Cable Bracket with roll pin must be Slit to allow the cable to fit into the Threaded Cable Mount. After being inserted into the Cable Mount, the Bracket with Roll Pin is reassembled on the Cable. The Slot can hammered closed afterwards(or even tack welded) The Caliper Hand Brake Cable Mount had to be enlarged to 5/8" from 9/16"(use Unibit) to fit the Hand Brake Cable Adaptor. Insert Cable into the Nut assembly with JB Weld Epoxy to fasten cable to prevent movement. Allow 24 hours for the JB WELD to harden. Drill out Adaptor to 5/8" to provide Cable fit. /inserting Cable into Adaptor with JB Weld to hold it. I Assembled all together With the Hand Brake completely Loose, Slide Cable Roll Pin with Cotter Pin over the Caliper Lever Arm while pulling cable. Note-Stainless Brake attached to Caliper with Bolt(with copper washers-above and below. 0 The Hand Brake Adjustment Threaded Rod must be shortened by 2 1/2". Just use a Hack Saw to shorten a non- threaded portion of the Adjustment Rod. Pic of the Hand Brake Adjustment Rod in Trans Tunnel. The Shorten Adjustment Rod will move the Hand Brake Arm forward and make it easier to access. Final Hand Brake Adjustment was made when all Four Wheels were on the ground to the point the vehicle could not be pushed be hand. Wheel Spacers- With my 17" x 11 1/2" Wide Wheels and Deep Offset, the Inner Wheel Bolts would contact the Ca[iper Outer Face. US Wheel Adaptors provided 1" thick wheel spacers which get about 3/4" Caliper Clearance. I can probably shaved the Inner Side of the Spacer about 1/2" to bring the clearance down to 1/4" Clearance if necessary. Bigger Brakes with Larger Calibers and Vented Rotors would probably fit now(trial fit to be sure) if you go to LARGER Calipers and Rotors. US Wheel Adaptors can make spacers to whatever spacing that you might need. Also, the spacers can convert to different wheel mounting patterns. Wheel Inserts with 5 Lug and 4x 4 1/2" Pattern Matt Cochan at LOVE20BEE IN California found Watanabe Wheel Inserts for me. I sandblasted and took them to a local PowderCoater to powder coat. Extended Lug Nuts- Because the Narrow Wheel Lug Pockets, I went to Ebay to purchased Extra Long and Narrower Lugs. Almost all of these 14mm x1.25 lug nuts had to been retapped with Exlarge Long 14mm x 1.25 Taps because of bad threading. Extra Long Wheel Lug Nuts on Extended Wheel Studs. Next-Struts and Exhaust Pipes

Driveshaft Modifications and Driveline Alignment- I sent my old Driveshaft to be lengthen as old R200 differential was longer than the New 8.8 Differential. I got the new measurement by inserting the Front U-Joint all the way into the T-56 trans. Then measured the distance between it center of Chevy U-joint to the center of the Front U-joint of the 8.8 Ford Differential. The Machine Shop will make the shorter by 1 1/2" . This allows space to remove the Driveshaft when it is installed. Note-How large the Ford Adaptor from Sonan is. Driveshaft installed-Rear View Front View-Driveshaft After installing the New Driveshaft was installed, the Drive Alignment was done to double check. I used Two Methods -1-using Spicer Drivetrain Products Application from the Web. It requires the use of a Digital Protractor(mine was Klein Digital Protractor from Home Depot. I think it was about $30 but I bought awhile ago. Front u-Joint Measurement. Second-Middle of Driveshaft Measurement. Third-Front Differential Measurement After entering the Three Readings, the Application gives a Pass or Fail Result. In this case, the Result was "Pass". The Second Method you use the Tremec Tool Box Application. I used my IPHONE to enter the angle measurements. The Result was "Pass" also. Half Shafts Installation- This pic shows the difference between the Datsun Half Shafts and the Ford 8.8 ones. Left Side(shorter one) Half Shaft installed. .

Once, you installed the Differential and Cage with the Support Bracket into the Two Vertical Mounting Bolts, the Two Forward Differential Mounts can be installed into the Transmission Tunnel. Left Mount Right Mount Note-Earlier 240z has mounting bolt holes close together so drilling an another hole maybe necessary(call Vlamir for assistance), Important Fact------My New Ford Motorsport Super Duty 8.8 Differential came with the Large Aluminum Pinion Flange so I had to fabricate a New Crossmember for clearance problem. I decided to modify the Original Nissan Differential Crossmember. Pic shows Sonan Adaptor on the Pinion Flange. Pic of 8.8 Differential with the Old Style U-Joint. Note the Close Clearance between Flange and Incredible Extreme Crossmember already. Original Nissan Transmission Crossmember taped and marked for metal cutout on top area. Cardboard Template of Aluminum Flange marking Side Cutout. Using 4 1/2" Cutoff Wheel to cut out Top Section of crossmember. Top Section of Crossmember removed.

Differential Installation- I had additional work on my house after painting it. Sorry again for posting delay. First, I Trial Fit the Rear Differential Support and the Cage before trying to install the Differential. The Trial Fit is make sure all the Fuel, Brake Lines and Hand Brake Cable does interfere with the Differential. Some Early Model 240Z , Nissan widened the Front Differential Mounting Bolt Holes. So make sure your Differential Mounts fit or you must slot existing holes or drill additional ones. Right Side Front Differential Mount Old Mechanical Transmission Jack for Installing the Differential and Support Frame Together. Installing the Differential- The Best Way to install the Differential is to preassemble the Differential and Differential Support with the Two 14mm bolts. This way you just have to align the Two Main Vertical Bolts with the Two Round Mount on the Support Mount. I used a old mechanical Transmission{ screw version) Jack. One person can install the Differential by himself. If you try to install the Differential after mounting the Differential Support by itself, you need other person to screw in the Two 14mm while you lift that 100Lb Differential- a difficult task. Also, early 240s with a Spare Tire Well, the well is close to the Differential Support on the Left Side Bolt and this 14mm can not even be inserted in. Some owner install Fuel Cells which are much smaller and allow the Left Bolt to be installed. The only problem with the Preassembly Way is the Two 10mm Outer Bolts in the Center of the Differential Support can not be installed with the Cage. So I drilled their internal nuts to 3/8" hole all the way thu the box crossmember. Then, install Two 3/8"x 4" long bolts from the top. Two 2"x 3" x 3/16" steel plates to spread the load over the crossmember top. Two 3/8"NC nuts under the Support Frame to complete this modification. Some people probably don't install this bolt but it is a structural part of this car. Pic of the Two 3/8" X 4" Long Vertical Bolts through the Cross Member. Closeup View Pic of the Nut inserted between the Cage and Differential Mount. Left Side View of Left Side Nut for Vertical Bolt. More Rear End Modifications coming up.

I found this video on visiting a Metal Supply Shop in Japan. While doing a S30 Fairlady Restoration, the Body Man needed more sheet metal to finish his job. This video shows a side of car restoration that most people never see- where the sheet metal actually comes from. The rest of the video shows detailed 240z body restoration It shows how to repair difficult body areas of the 240z. I hope you guys find this video interesting. Toolman

If your SU carbs were not modified to allow for the larger displacement motor, you might have a fuel problem. Meaning the carb needs to provide a richer mixture to run properly. You can try smaller SU metering rods which would provide a richer fuel mixture. But doing this may still not provide a rich enough mixture as the SU bore size maybe too small.

Ford 8.8 Super Duty 8.8 Differential Installation- First of all, I want to apologize for taking so long to finish this posting. I had to paint my house and had some other people's projects to help them with. The first thing that I had to do was to find a method of jacking the front end of my 240z high enough to use high jack stands. Because of the low ground clearance of my Rocket Bunny Front Air Dam and Low Vehicle Height, even my 3 1/2" Low Clearance Floor Jack would not fit. I solve this problem by purchasing a pair of 3 1/2" Car Ramps. They cost about $36 on Amazon. raises vehicle by 3" These ramps were about 28" long and would work on low riding vehicles. Short steep ramps would not work. They are very light weight and can be sacked together (taking a small storage space). jacking cross member The Ramps worked perfectly as my floor jack fit under the Front Cross Member easily. With the Car raised on Four Jack Stands about 6" off the ground, disassembly of the rear suspension can now take place. I designed my exhaust system for easy accessiblty. It consists of Three Sections-One -Front Motor Exhaust Pipes, 2-Middle Section with "X" Pipe after the transmission and Third- Rear 90 degree Exhaust Pipes with Two Turbo Mufflers. The pipes were also, connected together with V Clamps for fast disassembly. Next, the Two Rear Control Arms must be removed from the Strut Spindles. First, the Threaded Cross Shaft must be removed. The Tapered Shaft retaining Pins must be removed. With the Locking Nut removed, the Pins are removed by tapping them cafefully upwards. now, the Threaded Cross Shafts must be taken out. Because of Corrosion and lack of Lubrication, these shafts usually are difficult to remove. You can not hammer them out as both ends has threaded ends and hammering will damage the threads. ZDEPOT sells the Removal Tool but I made mine own. The tool consists of an Internal Threaded Rod which screws to the Threaded End of the Cross Shaft. The Larger External Tube( 1"OD" acts like a spacer of the Threaded Rod. A Large Nut on the opposite side of end of the Threaded Rod operates like a Forcing Screw to pull the Cross Shaft outward. I welded a proper size Lug Nut to the other end of the Threaded Rod. See Posted Pics for Size and Dimensions of this tool. Metric Lug Nut welded to one end of the Threaded Rod 15/16" Nut( pulling nut) placed on the opposite end of the Threaded Rod Removal Tool installed on Cross Shaft Rear Suspension removed With the Rear Suspension and Differential Removed, install the Differential Support Bracket on the two Long 17mm Mounting Bolts for Trial Fit. This test fit checks if any Fuel and Brake Lies and Hand Brake Cable are in the way. In my case, the Fuel Lines had to be extended and Hand Brake Cable modified.

This video is Part 6- This video follows the complete Paint Job of the 240Z. It covers disassembly and rebuilding of the Front Suspension. Some of rebuilding of suspension parts from scratch are interesting but normally beyond normal rebuilding process. But the video was made overseas(probably Northern European Country) where obtaining a Datsun Front Ball Joint is not easy like going to Auto Zone in USA. Though, seeing how parts can be created from scratch is informative.

As a exbodyman and auto painter, I agree with the previous individual about the rust condition of that particular FairladeyZ. The rust was definitely covered up with underseal and paint. What you can see, is only about half of the real problem. Having rust work properly in Japan would be very expensive as there are only a few Japanese Body Shops that specialize in rust work. Majority of them are located in rural areas of Japan. If you still wish to purchase your Z in Japan, you try to find Z car guys and make friends with them. They should know about Z prices and places to work on your Z car. Places like UP Garage in Japan sells "second hand" auto parts at almost half the cost as compared to the US. Z body parts are a different story. Because the Z is so popular now, there are many suppliers for z body parts. Z mechanical parts in Japan tend to better quality than Chinese parts if you can find them. If you are interested in restoring a Z, check out Restoration of Z Cars on You Tube in both America and Japan. If you don"t have body fender and mechanical skills, your best option maybe to wait to return to the US and find a Z car in the Southwest part of the US. Places like California, Arizonia, Texas,etc, their drier climates will provide you the best chance of finding a Z with little or no rust problems. Good Hunting!!

Ford 8.8 Super Duty Rear Differential Conversion Kit for my 71' Datsun 240Z There are several different companies that have Ford 8.8 Differential conversion kits for S30 and later model 260 to 280z. However, most of them utilize the earlier model of Ford 8.8 Independent Rear Suspension from mostly 2005 Ford Explorers,Mercury Mountaineers and other SUV models. These differentials can handle 400HP and some even have Limited Slip in them. So they have been utilized in Drift Cars,Ford Trucks, JDM Cars and even BMW Racers. But, finding one is difficult because high demand and limited supply. Fortunately,a New and Stronger Version of the 8.8 came about-the# Super Duty 550 Differential with started to appear in 2015 Mustangs with Coyote Motors and Eco-Boosted 4 cylinder cars. This differential can handle from 600 to 1000HP ( with beefed up). It weighs over 100 lbs and comes a Torsion Limited Slip. I ordered my Super Duty 8.8 from Summitt Racing for $1300with 3.55 Gears. + shipping. At the same time, I ordered the Sonan 8.8 Drive Shaft Adaptor from Summitt Racing for $179. They manufacture Two Versions of this Adaptor. One for Manual Trans and One for Automatic Trans. The difference is the existing Pinion Yoke Size. My 3.55 pinion takes the Automatic Trans Yoke Adaptor. It is constructed of Billet Aluminum and handle alot of horse power. This adaptor costs about $179.

I manage to find two pics that show Model Displays of Scale Motors at AutoBacs Store. Note -the prices of these motors are shown in Japanese Yen. To convert the price into US Dollars- just divide the Yen Amount by 150. The 150 is the Current exchange rate in Japan. One US Dollar is worth 150 Japanese Yen. These Motors have actual cranking movement driven by a small electric motor. I finally found the K Van pic.
