c20 to c10 u joint

[72slam]

Can some one tell me what kind of u joint I need to go from a c20 drive shaft to a 1/2 ton rear end. I've heard it talked about on here before somewhere. Is there an item # or something like that I can tell them at the counter. They know what I want, just not where to look. Thanks

It will depend on which yoke is on your 12 bolt, a 1310 (3 1/4" wide) or a 1330 (3 5/8" wide). the drive shaft should be a 1350 joint

One of the following should work:

1310 to 1350: Spicer #5-460X or Neapco #3-3140
1330 to 1350 Spicer #5-134X or Neapco #1-0134
