yea man. find a 14 bolt SF 6 lug out of a OBS 2500LD 4x4. a 2wd rear end is narrower by 3 inches. it could work with some 1.5 inch wheel spacers. thats what i have now.

Really don't want to run any spacers, is this something that if I found out of a 4x4 version would directly bolt in?

Mine is a 8.5 10 bolt with 30 spline axles...the one I am after is a 14 bolt with 9.5 gear, and 33 spline axles from what I have seen.

Thinking of doing a denny's driveshaft with the swap as well so that wouldn't be an issue as I would go for both 1350's
