what clutch cylinder did you use?


Master cylinder?
I used a late 80's - early 90's Nissan Pathfinder.
Less than 25 bucks and performs as good as a Wilwood.

Any part nr for the t/o bearing?


Go to their websites.

does anyone know the area of the piston in the t/o bearing so i can calc the needed clutch cyl area?


Don't over complicate this area. A master cylinder with a 3/4"+ bore will work.

also what is the stock mec link ratio?



The instructions for clutch pedal throw come with the units. I believe they are also on their websites.
