I just finished putting a rebuilt T5 out of a 1986 Turbo coupe in my 1976 Mustang II. I picked the Turbo coupe T5 for the .405 first gear to help get it rolling quicker. The C3 is a slug, in typical 70's fashion it wants to shift 1-2-3 by 20 miles an hour anything short of flooring it. I spent the good part of the year rounding all the pieces up. I had the flywheel surfaced, lightened and a new gear pressed on. I bought a pedal assembly on Ebay. I didn't know there is several different assemblies available. I got an assembly from a V6 car. The pivot for the brake pedal is different. The four cylinder pedal pivots on the lowest hole in the support. The 6 cyl. pedal pivots on the top hole closest to the driver. I took the auto pedal out and recontoured (heat and bent) the pedal to match the configuration of the 6 cylinder pedal, then carefully cut the large pedal off the arm. I cut the small pedal end off the V6 arm and welded it to the reshaped auto arm. Now the pivot for the brake and clutch is the same and I can use the stock bolt. When I got the
trans in the car the shifter was 4" forwards of the stock location. I found a web site showing a shifter extension by MN12 performance. They are no longer in bussiness and at $400 I could never afford it. However, looking at the pictures, I figured I could make one. The first one I made was very similar to the pictures but didn't work (I don't see how theirs worked either.) I put a bearing in the rear and changed the pivot point lower in the extension block and it worked great. I posted pictures on my profile. Now the shifter is in the stock location. I changed the shifter to a Hurst from a later Mustang and it is very tight and short throws. The 5 speed works very well. The whole car feels much more lively. Take off is better and freeway driving is much better. I have 3.55 gears and 50 series 17's. Before I was seeing 3700 rpm at 75 mph. Now I'm at 2800. The car is much less busy at freeway speeds and pulls 5th just great. I am waiting for a module for an old Mallory mechanicle advance distributor to come in. Then I can put the sidedrafts on it then. I am looking for a good oval port head with no cracks to take to the machine shop. I have big valves, springs retainers, roller rockers and a Ford racing A237 cam to put in it. I want to take .060 off the head to bump up the compression.
