anyone have this problem (clutch not releasing fully) on a stock '49 Chevy 3600 with a 1954 motor. Stock 4 spd. With engine running I cannot put trans into gear. I have adjusted the pedal linkage as far as it will go. New clutch disc, pressure plate, and throw-out bearing. Flywheel was resurfaced, but not much taken off. Would really HATE to pull this trans out again as it is very heavy and has a lop side bottom making it difficult to support on a jack
