If i'm reading that right, all 3100 and 3600 (1/2 and 3/4 ton trucks) have 10 splines on the tranny side, and on the 3100 the rear of the joint has 17 splines, and the 3/4 ton has 10.
Since there dosen't appear to be any mention of 3 or 4 speed, I guess I can assume that the same joint was used in both the 3 speed and 4 speed trannys.
I absolutely know for sure the '46 2 ton dosen't use torque tube crap.. this chart dosen't seem to have any mention of which models used torque tube and which didn't.. so now i'll just have to narrow down what year(s) the part I have will fit.. maybe I can find somebody who needs it.
