Reply to "clutch Release bearing"

You can do some measuring, but, yes, I believe you will have to do something with the hub. Generally, diaphragm clutch fingers stick farther out than the old three finger ones. On my car, even with the throwout bearing all the way back, there was no space between the T.O. bearing and the pressure plate spring. I modified my hub on my lathe to get clearance, but an easier way is to buy an adjustable hub (from P.I. of course). And because diaphragm clutches require more movement to disengage, I had to go to a long throw slave. It's all worth the effort, though, because the pedal feels soooo much better. Anybody else have different opinions on this? -Steve
