JWT clutch is just too damn good... unfortunately...

In most Valeo CSC's the piston is plastic, then on top of the piston they mount the bearing, a tiny little diaphram spring, and the bearing retainer which has like 8 little fingers that snap through slots on the piston and hold the bearing onto the piston. then the zspeed csc gets glued to the bearing. I've actually posted photo's of the stock assembly dismantled i think they are in this thread somewhere.

Edit: also it's none of the companies you listed, i checked with them but all their hydraulic throwout bearings were way to tall. If they agree to make the parts for us and at a reasonable price i will throw it out there.

As for the distances not off the top of my head i know the factory clutch has just under a half inch of throw, and the setup height of the factory csc is right around 1.8 inch from tranny to pressure plate. I have extra clutch and flywheels sets at my disposal to work from i haven't gotten around to measuring all of them yet.
