Hydraulic throw out installed. That created a few issues. McLeod requires a 0.100 - 0.250 gap between the bearing and the pressure plate fingers. The standard piston was too short. To remedy that, they sell a tall piston. After I installed the tall piston, I had less than a zero gap. To fix that, I needed the trans moved back 3/16". Which would now get me past the minimum and give me the 0.100 and some change. That would still leave me with enough pilot bearing interference and full spline contact on the disc. So that nice 9/16" thick adapter I bought now needed to be 3/4" thick. Off to the mill I went.
Next issue, the throw out bearing stack is too short to pilot into the bellhousing. So I made some bolt-on line-up blocks that are bolted on top of the throw out bearing base. Leaves me with an extra 1/8" protruding from the adapter to keep things lined up in the bellhousing. Makes me feel better about the driveshaft since it was built slightly shorter than I wanted.
