When you and I spoke, I don't recall if you said you have the short input shaft or not. I think my setup (short input shaft, no transmission spacer) is similar to yours, except I am using the diaphragm style ram clutch, not the finger type.

The distance from the bellhousing face to the fingers is 2.52" I finally got to someone at McLeod. Spoke to Billy at McLeod and he says to use their #1364 and it will work. But I don't have the warm fuzzy's.

From their site, appears to be a good choice but I don’t have a lot of confidence in them or it. Asked him for the effective area of the piston in the bearing and he couldn't tell me. Gave me a suggested master cylinder size and stroke (3/4” x 1”), claims that will generate enough fluid to operate clutch. Says it needs 11cc to move .7” When I do the math on this, it doesn't work out. I challenged him on this and he said, “Oh, doesn't matter, you have to pump the pedal a couple times, then it works”. I am an engineering type so the numbers are important – have trouble with “guesses”
I have been told by another forum user that the #1364 works - I 'm just not ready to invest $400 to find out.

I have a copy of their installation instructions, if you want it.

I have tried the Ram unit and it doesn't work - too tall. Spoke to the guys at Tilton and they told me up front their's won't work on a short shaft version - it's too tall.

Looked at the Exedy unit, but couldn't find any dimensions to determine if it would fit.
