i posted in trans section, haven't gotten much response. it looks like i need a new clutch before i put the engine back in my car. stock 302 with m21 what is everyone using? diaphram, borg&beck, or other suggestions.
not a race car i just want it to work correct.

stock was a 10.5" diaphram clutch. A zoom or hayes hiperf would work pretty well.

I also have a 68 Z/28 with 302, 3:73 posi, and stored the M-21 and installed
a M-20. I use a Center Force Dual Friction. Its a diaphram clutch; stock pedal feel; and engages very well with no chatter. "Bites " very well, and can throw a shift at 7000 rpm with no problem. I highly recommmend using one
