B Body 8.75 in a an body

I did it on my '71 swinger, it does fit and right now I am running some stock 5.5 x14in rallys with 205 70 14s I believe. I haven't yet measured for the new wheels but I am going to have to have a custom made wheel with a lot of back spacing. As far as spring perches go I left them in their stock location because I am about to do a spring relocation so I didn't sweet the little bit that I stretched the springs.
