This is the one I'm currently using. http://www.summitracing.com/parts/WIL-260-6089/ it only has 1.4" stroke so using the math: 4416 (3.4”) / .6013 (7/8”) = 0.7344 then 1.4” (pedal stroke) x 0.7344 = 1.028” (fork movement) This setup actually measures @1.1" at the slave on my car currently.
i am going to go with this setup --- it should be good this is what every body uses that did the T5 swap http://cnc.carshopinc.com/product_info.php/products_id/13667/711-3/4 http://www.carshopinc.com/product_info.php/products_id/13655
Hydraulic throw out bearings typically are installed with 0 lash, meaning they can have a little bit of pressure on them. They should have shims to space it out. Im using a 3/4" master and my throwout bearing is a 1-1/4 max movement, and it works just fine with a stock Ford T-5 Ben
