It seems that I'm starting to collect transmissions. I now have 1 atx, 2 3.94's and 1 3.55.

The 3.55 has Marks old ERT retrofit installed. I decided to put this one in the car.

One thing to note, is that the arm I've been dealing with is shorter (from center to center) then the one on 3.55.

So I plan on seeing how it is with the current arm, then switch to the shorter one and measure the difference. Also, the 3.94 has the beefier case with the webbing on the back half, and the 3.55 doesn't. So I might gut the 3.94, have the case PC and put the 3.55 internals in it.

Btw, I did end up cutting the weight off and everything fits fine.
