5 - 178X if it has 1.188" cups and outside snap rings ( more common with 400 turbo trans in 1/2 ton)

5 - 3147X if it has inside snap rings. (more common in 3/4 ton)

Spicer changed all of their part numbers within the last year when they updated those joints.
5-1310x
5-1350x
I can't recall what the part number is for the 3r joint but I haven't seen a 67-72 with 3r joints yet.
