New clutch setup won't disengage

Got a one-line response back from Brewer's ("Wayne/Dan") : "You'll have to mock it up and see". Doesn't help much. Was hoping they knew the fork ratio, that would provide part of the answer. I sure don't want to remove it for measuring, because I might never get the throwout bearing reattached without pulling the trans!

Still waiting to hear from Centerforce as to how much finger movement is needed.
Anyway I'll be home this weekend and see how far the fork is actually being pulled.
Proof positive that customer service stops when the money changes hands!
