Sal,

I used Tilton master cylinders on mine after talking to a bunch of racers that had problems with other brands. They are available in a bunch of bore sizes and reservoir options as well...and come with all of the reservoirs in the kit. I don't know if they'll fit for you, but I'm happy with mine...all 3 of them.

One of the guys I spoke with used a composite master cylinder and had the thing blow in half at the knit line on his brakes...hit the wall. After that story, I was rather turned off by the composites.

As far as bore size, I can't say for your car. In my case, a 3/4 is barely enough to disengage the clutch. I'm using an internal throwout bearing type slave...valving is probably different. I tried using a 5/8" bore to make the pedal effort real easy; it didn't move enough fluid. 7/8 would make the pedal effort even harder than the 3/4 and would cause the slave to throw further.

I'd also make sure you're not exceeding the travel limit on the master or the slave. In my case, I had to build a custom stop for the master to avoid throwing the slave too far...which can damage it. This might apply to you as well, I'm not sure.
