I modified a CRII pedal box for no throttle (electronic now) and hydraulic clutch! With only 700 miles the clutch master cylinder failed! It was a Wilwood 7/8"! This is for a GM hydraulic throw-out bearing. I didn't like the feel of it but it seemed to be moving in/out pretty straight, with no binding and I had a stop! To reduce pedal movement I replaced it with a 1 1/8" Wilwood, I like it even less!
Thinking of going with this:
