i have a '33 ford rear end and need to shorten the torque tube and shaft. i have searched but nobody has done one of these it seems. i know how to cut the tube but what i was wondering about was the shaft. it is a roughly 1.500 dia tube and it appears that the input trans end is welded on and the rear part has a splined part welded on. can i just grind the weld out from one of the ends, then shorten the shaft the required amount and weld it back in?
