Challenger rear in an A body

1970 8.75 Challenger rear in an A body. Whats it going to take? Move spring perches and a hefty backspacing on the rims?????

I got myself an e-body rear in my even tighter early-Abody. It look some custom wheels with a large backspacing to fit, but it works. If I was to do it again, I would try and find a early b-body rear end though - just makes life easier in-terms of finding a set of wheels.
