Since I am a cheap bastard, and the master and slave cylinders that were on my RX7 were basically brand new, I decided to try using them on my 351 / T5. A simple bracket, 15 dollars worth of brake lines from Autozone, 1 dollar brass fitting from Home Depot, and about 3 hours of labor. I replaced the pushrod with an allthread bolt, and using two nylock nuts and washers to secure the Ford factory pivot arm (updated since picture.) I was really pleased with the result, clutch feels effortless, like it was still pushing the Mazda clutch. And adjustable.
Snazzy, that's an innovative (and really cost effective) idea.
