i just got a ford 9 inch with a 1330 yoke, i would like to keep this yoke. i am running a aluminum driveshaft with the stock u joints. i need to know which u joint i would need to go from the stock drive shaft to the 1330 yoke. i know the driveshaft needs the lock rings on the inside and i think the 1330 yoke needs the inside lock rings too because the 1330 has tabs on the outside of the yoke. thanks for your help

 

Your local NAPA will have the conversion u-joint that you need. They run about $20.00.

 

Spicer part number 5-212X works if you had your builder use a Ford motorsport pinion yoke.
