Jim,
I think you are asking about the possibility of using a set of 3.55 gears out of a 1951 car Powerglide in a 1954 1/2 ton truck.
The answer, I think, is still: the gears out of a torque-tube Powerglide will not work, no matter what carrier you may try to use.
If that answer is wrong, maybe someone will give a clear answer on what parts from what source will work with a 3.55 R&P set from a Powerglide 1951 car installed in a standard 1954 1/2 ton truck rear end?
