Changing clutch on '91 Ex, need help please!

One more thought--I will never understand why Ford decided to use the M5R1 instead of the T-5. Not that I've had any problems with the M5R1, but mine does see rather light useage. Judging by the input/output shaft size the Mazda is FAR weaker. It also manages to be much larger somehow. The T-5 is one of the most widely used transmissions with TONS of gear ratios to select from, is smaller, lighter, and VERY easy to rebuild. Since its so common, it may have been cheaper to use, too. all that would have been needed was a dedicated bellhousing, flywheel, and TC adaptor. Its actually also a pretty slick shifting piece too.

Heck, it could be retrofitted to a 4.0 with some effort. A ~3/8" thick bell housing adaptor would be easy to make. Since the pilot bearing is in the flywheel and the flywheel pilots on the crank, you could have a corresponding flywheel spacer turned that would maintain the piloting relationship. The spacer thickness would need to correspond with where input shaft tip's final installed placement would be (easily added up from measurements). If you adapt a GM bellhousing, you could use existing & readily available slave cyl, fork, & TO bearing. A shop that deals with hydraulics could make a custom line that would connect the Ford m/c to the GM slave. Add AA T/C abaptor, and voila, 4.0/T-5 combo.

Sorry, I haven't shot ducks in a while.

There is a company called advance adapters that makes and adapter for the T 5 i believe.

Anyways, your question about a clutch petal, no you have to have the whole assembly to with the 2 petals, brake and clutch. The master cylinder hole is already there, it has a rubber plug in it's place. Everything in the swap is bolt up.

The AA (advance adaptors) adaptor just replaces tailshaft housing with one that mates to the 1354 T/C--hooking it to the 4.0 is the difficult part as there is no bellhousing for a 4.0/T-5 as far as I know.

It was just a thought (shooting ducks ), I don't think its a practical swap if you want to keep the 4.0, and I think if I were to go through this trouble try to add a T-5 I'd have a 5.0 in front of it (I LOVE the HO 5.0).

I am definitely glad to hear that the hole is there on the firewall already--that was the worst part about the Trans Am swap (I've even had to go back in there and adjust the position by elongating the holes, ugh). Though I'm not happy about having to swap the pedal brackets, I'm glad I will have a comeplete donor for when the time comes.
