3/4 ton axle swap

[Magic1]

Hey guys. I was just getting ready to rebuild the front and rear end on my 82 GMC Sierra k10 when I was lucky enough to come across a good set of 3/4 ton axles with the same gear ratio that I was gonna put in mine when I rebuilt them. The question I have is does anybody know what the part number is for the ujoint I'm gonna need for the rear swap. I've heard it called a hybrid and another word I won't use here, lol. I know this has been done a thousand times so I'm sure I'm overlooking it somewhere but I can't seem to find it. It would be way easier to have a part number when I go to the parts store instead of trying to explain to the kid what I'm doing. Thanks in advance. It's a 12 bolt now and going to a 14 bolt ff if it matters.

I think it should be a 1310 u-joint for your old axle and a 1350 for your 14bff.  http://www.summitracing.com/parts/pcn-348
