u joint

Anybody know the spicer part # for the ujoints on a jet coupler? I have the smaller one, everything I read says its a 1310 series. problem is all the local part stores (NAPA,CARQUEST) tell me the 1310 has outer locks.
mine has inner locks. I would like to locate one before I tear it down.

for 1310 I get 1973 chevy 1/2 ton truck u joints. sounds like you need some u joints from a late 70's camaro I hope this helps if you need 1350's a 73 3/4 ton chevy will work

I have taken the u-joints out and to the Auto Parts store and had the guy behind the counter pull 3 or 4 and then match them up there. They don't like to do it when they are busy but go in there on a weekday and they should be able to help you.

Spicer series 1310, outside snap ring: Spicer PN 5-153X, cap to cap= 3.219", cap dia= 1.063"
Spicer series 1350, inside snap ring: Spicer PN 5-178X, cap to cap= 3.622", cap dia= 1.188"

Thanks for the info
