Need some help guys. I was ready to fire up the '53 3/4ton today for the first time. New 235 block, rebuilt engine, new clutch, etc. When we went to push her out of the garage to start it, the only way I can move it is with the clutch in. When the shifter is in neutral, it is still in gear. The tranny, clutch etc were all put in within the past 6 months. The flywheel was resurfaced, so I'm thinking it isn't likely that the clutch disk is frozen to the flywheel. So what else would cause it to stay in gear when it is in neutral? This is a Saginaw 4-speed on the floor. The gear shift moves freely side to side in the neutral position, but it is still in a gear. Help please.
