I think the rearend is a Ford rearend, the pumpkin is offset towards the passenger side not in the middle. I'd like to swap it back to a Chevy rear, preferably a 10 or 12 bolt so I can use the rear disc set that came with the kit I bought before I knew about changes that were made.
I'd like to know if the rear end was moved back so if I decide to go back to an original bed instead of the utility bed I just cut off there won't be any (more)surprises.

I'll try to get pictures up tonight.
