Trying to help my friend ID the transmission in his 1955 first series 3104 pickup. So far everything looks correct but this trans looks wrong to me. I haven't had a 3 speed in a long time, and what I had was a 54 that had a torque tube. I know that my tailshaft housing was completely different. Much shorter. I was under the impression, that as the 1955.1 supplement states, that the 54 trans was only modified to be able to use the hotchkiss type u-joint. This trans looks like it would be of a later type.
The case casting number is 3845122, and the tailshaft housing number is 3707196 if I'm reading them right.
