Well, I just finished test driving the car with the new clutch. The first thing I noticed was no more clutch chatter in reverse. That was getting annoying. The clutch is a lot lighter and releases quick. I like it.
What I ended up buying is a Spec clutch kit. It's a 12" diaphram pressure plate (replacement for the 11.5" stock style), disc, release bearing and pilot bushing for $299. Everything was right except they sent a pilot bushing for a small block.
I found as I was re-assembling the bell housing and tranny, that the pressure plate hits the stock cast bell housing just forward of the clutch arm hole. I had to take the trans back out and remove the bell housing to grind off about 3/16" of material in this area. Works perfectly now. I e-mailed them and expressed my disappointment at the fact they had no idea this could be a problem and they said it would absolutely fit. Other clutch companies have obviously run into this, as they have disclaimers on their website saying the PP may not fit a stock cast bell housing.
Anyway, I'm happy now with my purchase, and the old car is good for another several thousand hard miles.
