8.75 Brake ???
Why did you change backing plates? If you have 10" backing plates on an 8 3/4, and you buy new LBP axles, you shouldn't have to change backing plates. You can buy axles from Moser for under $300, which are stock A body length, and use your original brake parts. Just redrill the drums for LBP. I did all this on my 70 Dart, no problems.
