10 Bolt to 12 Bolt Ujoint ?

[01mudslinger]

I have a '88 Gmc Jimmy with a 700R4 and i just pulled the 10 out today and put the 12 in, but the ujoint wont bolt to the rearend yoke, i read something bout a conversion joint from Napa or something, does anybody have any ideas or maybe the Part # would be nice. Thanks for your help.

Sorry no part# but if you go to your napa parts store with a cap from each yolk they have u-joints like what your looking for they hooked me up with one for a 10 bolt front and 1ton front shaft and they had it in stock!!

Or just swap the yoke.
