Factory 80 trans am 3r diff yoke 2 5/8"
80 Trans Am Strange CM diff yoke 1350 2 7/8"
Attached is the Strange 1350 CM diff yoke....once you go from the 3r funky retainment to this...you feel pretty comfortable.

thanks for measuring it. so it looks like about 1/8" for the pinion yoke & 1/16 for the Ujoint, 3/16 total difference using the 1350, shouldnt be an issue if the shaft length can compensate for that.
can anyone confirm what rear joint a 72 firebird with 350/350 used? i will measure to confirm before i order but i always thought it was a 1310 that uses the straps to hold it in the diff yoke that has centering tabs. did they change to a smaller u joint for later years, is that maybe the 3R?
