Pedal rod to Z bar question.

Yes I already put the Z-bar bushing,seal,washer,lock spring kit in. My issue is New clutch ,PP and throw out B. I can adjust clutch with pedal really low on floor but pedal won't completely return. I did put a stiffer spring from z bar to pivot arm to try to help .If I adjust pedal higher I will go (over center?) which I did once and popped the spring retainer on throw out bearing.(That was fun fixing) I would have to put a block under the pedal or Fab. a stop if I want my adjustment at top of pedal.

So to get what going on correct, it all worked before, then you replace the clutch, pressure plate and throw out bearing?
