8 3/4 help!!!

Took the housing apart on the weekend.. housing ends measure up same as the newer 8 3/4 so that should be good..

Questions??
1. if I keep the b body length... I think I will have a hard time finding a 6 inch rim that has the 5 1/2 inch backspace I would need.

2. If i shorten the rear end, I am thinking 2 inches each side.. the b body rear measures 60 inches ( axle face to axle face) , while the a body rear is 57 1/4.. will that small decrease in overall width make much difference.


I can get the backing plate to drum hardware easily enough, and will have to order special length axles LBP to fit

Does this make sense?
