1987 Rear swap help
Need some help. I have a 1987 chevy R10 10 bolt 5 lug rear and I want to swap it out with a 1976 Chevy 12 bolt 5 lug rear out of a C10.
Can anyone tell me the U Joint spec sizes for these? I am coming up with the dimensions but not the diameter of the caps. 1987 - 1.13X1.13 2.37 x 2.37 outer 1976- 1.06x1.06 3.22X3.22 outer I am assuming this are not interchangable and I will need a special u joint for them...
