Ok, i finally got the engine out, checked the diffs (i heard an account that was identical to mine in which the prob was the diffs, but my diffs looked like new) and it definetly is the clutch, its was worn down pretty bad and it was glassed over, im not going to bother with sand paper, just replace it.

My question is, is it worth it to replace my 2 shoe nylon clutch, fitting flywheel, with a flywheel that will use a 3 shoe clutch setup for aluminum shoes?
