I measured the U joint wrong. Solution?

Well I ordered a custon DS and a SYE kit. Apparently my yoke on the rear diff is 3 7/32 and I measured 3 5/8. Do I have to get a whole new driveshaft or can I order a new yoke for the rear difff so that it will fit? I really dont want to have to get a new DS.

Thanks for the help

Did you try to eyeball it? That is a huge difference. What diff do you have?

you could get a bastard u joint for the rear.

No im retarded and was in a hurry and measured the caps or whatever as well so it was naturally larger.

Explain, I wanna try to get this thing on the road the quickest way possible for me.

This should be what you need

I dont need to make the u joint larger, its the joint thats too big for the pinion yoke.

flip your monitor upside down, it should work then.

Well im unsure of what that is. But do they sell the 2 different size pinion yokes for the 8.25?

Here are several yokes I found, im not exacty sure which one fits a 1350 U joint though.

The pinion yoke requires a 1310 ujoint - 3 7/32" cross 1 1/16" cap.

The 3 5/8 measurement you gave could be either a 1330 ujoint or a 1350 ujoint.
1330 - 3 5/8" cross 1 1/16" cap
1350 - 3 5/8" cross 1 3/16" cap.

You need to measure and determine which do you have on the drive shaft a 1330 or 1350. Then you need to buy the correct conversion ujoint.

1310 to 1330 is a spicer 5-134x ujoint.
1310 to 1350 is a spicer 5-460x ujoint.

The conversion ujoint will allow you to install your driveshaft as it is.
