I've got a 99 Sierra rcsb that I'm doing a 80 swap in. My yoke is about 3 weeks out from Jake's from what I was told. So u was wondering if anybody knows the length of there ds that has done the swap. It would really help me so I can get the ds made while I wait on the yoke.

Thanks for any help.

 

Set the truck on blocks or something measure from tip of tail housing metal part not the gasket but the actual housing then to the face of you pinion yoke were the bolts go I went with a pst piece used a strange 1350 yoke with a k5 pinion seal and sent them the measurements they had my shaft made in a day 349.99 1000hp rated

 

Mine is 4x4, but had it shortened 1 and 11/16 of an inch.
