It is the same clutch fork. I pulled the collar from my T5 and 2 collars from 77-78 transmissions. The collars are the same on those, and they are LONGER than the T5 collar. This doesn't make sense to me. If I'm getting less than enough throw right now, how can a SHORTER collar help me? To make sure I wasn't crazy I pushed on the fork in one of the spare transmissions from the front, the same way the piston pushes, and it moves the collar forward (towards the front of the car.) Replacing the collar that is presently in there with a shorter one would reduce the amount it is pushed forward, the same effect you'd get if you didn't push the pedal down all the way. And yet, this is what all these sites are recommending I do.
What gives? Surely there are a few people here who have put a 240mm clutch, pressure plate, and flywheel on a coupe. Please let me know what's going on.
