Transmission Cross member .......This has peak my interest..........I have owned 5 AD trucks all 1/2 ton short wheel base over the years ( all of unknown history). Not one has had a rear transmission cross member. Suspect all were lost over the years ?
A little research does indicate there should be 5 cross member on all trucks. See attached My 1950 GMC 100 only has 4 as it sits. Engine trans support diagrams do not really show the rear of the trans but only give the torque tube function. See attached
I am not going to look for a transmission support member as it appears to function fine as is.
