Which hydraulic throwout bearing?

I got mine all set up, installed, and there is over a 1/4 inch between the fingers and bearing face. So I called AmericanPowertrain and told them the solid spacer is too big and the 5 shims was not enough. They are sending me more shims and a longer stud. Hoping this will get me the clearance they call for, .150-200.
I had to machine the solid spacer down to get the clearance needed.


I hunted every where for a hydraulic throw out bearing for my 18 spline and never found anything to entertain my ideas. So I settled on the American powertrain kit with peddle and throw out bearing.

I was also going to recreate the mounting setup for the master cylinder.
