I just found this pic of pressure plate / clutch thats in the car (that my friend installed), if anyone can see anything wrong here please let me know thanks!
This DOES bring up an old memory: Are you SURE the clutch / pp works OK regardless of the slave setup?
In the '70's I put a 10 1/2" Corvette diaphragm pp in my 340, and it would not release. The pp was JUST PLAIN DEFECTIVE. I fought it for a week, and since it was an adaptation, we kept thinking "some ting wong". I finally exchanged it for another just like it and it just worked GREAT.
If you have access to a large enough press, "rig" the flywheel, disk and pp in there with something to mimick the T.O. bearing and measure how much movement it takes to release it. Verify with at least a .040--.060" (inch) feeler gauge
