Hello, not sure I'm posting in the right place but I am currently rebuilding my mustang for the first time ever. I have a 1971 mustang with a 1969 351 windsor, but I'm swapping the trans with 1991 T5 manual, pretty Frankenstein. The transmission has an adaptor plate to use the original 1969 transmission bellhousing with the 1991 T5. Now the clutch and flywheel is what are confusing me. I am not building a racer or a drag car so I'm looking to go super expensive but still would like some quality, I've been looking at Napa parts mostly, little better in quality the Autozone in my opinion, but I'm not sure what clutch and flywheel is needed to make this swap work. I have the original 1969 flywheel and clutch but the clutch is pretty shot. So if I'm replacing the clutch i might as well the flywheel. But do I need a flywheel and clutch for a 1969 or a 1991 since the trans is a different year, or does it even matter?

 

CoSch90, pulled this from my notes from "back in the day." Hope it helps. There are several ways to go if you desire a five-speed manual in your '65-'73 Mustang. That's why we thought a review of the process and a step-by-step look at the method we chose were in order. With a T5, you can use a late-model T5 bellhousing along with a cable clutch linkage conversion kit, or you can use the car's existing four-speed bellhousing and run an adapter plate to join it with a T5. In the case of our subject car, we went with the latter.

The conversion was done on a '69 fastback equipped with a 351W and a Top Loader four-speed. If your car already has a manual transmission, you can procure the parts for the swap from California Pony Cars. As for the transmission itself, National Drivetrain is an excellent resource, with its Platinum Torque line of rebuilt transmissions, including the venerable T5 five-speed, as used in some form or another in Fox-body/SN-95 5.0s from 1983-1995. We've already driven the car extensively with the Platinum Torque T5 in place, and it shifts and functions as new. What's more, there's a full one-year warranty included, and you'll save about $200 over the cost of a comparable brand-new T5. As for the clutch and pressure plate combo. I suggest calling Summit: 1-800-230-3030. There is a cool RAM combo that I think will work for you, with your project.
