I have the used 10" flywheel and new pressure plate/kit mounted. And have the throwout bearing/ bell housing/ tranny together and ready to put it back in. I was making some demensional checks first and found the following:
I estimate the thowout bearing will not start to push on the pressure plate fingers till it is flush with the end of the bearing retainer collar. The throwout will only push about .25" on the pressure plate fingers fully dis-engauged (as far as the fork will go). Does this sound right?? Is that enough to dis-engauge the clutch?

The pressure plate fingers are about 3 1/8" off the block surface (mating surface for the bell housing).

Thanks, Clyde
