Info on 7.25 to 8.75 backing plate swap

No.

There should be a bunch of the small pattern rear brake setups floating around from people swapping to big bolt pattern. Post a wanted ad and see if anyone has some. Maybe try Moparts, too.

I might have some, but I'd have to go digging, and I'm not sure if I do or not. I know I have one set, but I need it for my wife's car.
