bad vibs....

With that much free play in the clutch and the pressure plate and throw out are still touching enough to spin up the t.o. at speed then it's really time to start thinking clutch pack, t.o., and resurface. Could be now the pressure plate is worn now enough it's still making partial contact with the t.o. even with proper adjustment or the t.o is wobbling enough to make contact. How long had it been since the clutch had been adjusted?
Pop also wants to know if you have put a clutch pack in or are going to how much wobble is in the input shaft of the tranny...also check the bushing in the crank.
