F body 8 1/4 into an A-body

I had one in my car when I bought it, so I'd say it can be done. It's pretty much B body width overall, perches need to be moved and changed too if you want to use old shock plates. The F body stuff uses rubber isolator pads on the springs that use giant locator holes in the perches. If you move them in to A body length though you can just get old perches with the small holes when you replace them. I think driveshaft length is all in the center section and transmission, so it should be the same as any 8 1/4 I would think. May need different offset wheels to take up the width difference, but I think there are some stock ones out there you could get by with.
