Yukon A-Body Axles / C-Body Brakes

I have never used aftermarket axles, but both of my sons' cars have shortened C-body axles with station wagon 11" brakes (The Dart has 11x3s and the Barracuda has 11x2.5s). There were no fitment issues on the Dart and the Barracuda was missing all of the parking brake stuff from the handle back so we pulled the parts.
