I think its a 1310 , i took the caps of and measured the trunion comes out to 3inch.. also the U-Joint has numbers on them SPR F1 89N ZZ, or its SPR F1 N68 22, end caps are stamped Spicer P051
does anyone knows if Spicer 1310 is the same as Spicer 5-153X??
this truck is a total mystery...When i got this bad boy under the hood already had a 283 with a 4speed , 3 Universal joints with a center support..Im sure its not original also.
keepen me on my feet for sure tracing what parts came from what car/truck!
