I have 51 chevy 1/2 ton that has a 235 engine with a 4 on the floor. Thing is that I dont want the torque tube because of the fact that is has really low gears and I would to like to change it out for a later model rear end.

Any trans/diff combos that would work fine with the 235? I also have a spare 250 engine with trans(don't know what kind) off of a 79 chevy van. Plus a rear end off of a 1987 chevy truck 1/2 ton.

Would any of these parts work together? ohwell Thanx in advance
