a center section is a center section...A..B..C or E body....
if you order the axles from Dr. Diff...you do not need to cut anything...
back plates....???...you really want to run B body backing plates which will allow you to use the large bolt lug pattern without any other modification....plus as there are no A body drums that will fit a LBP without drilling them....both the drums and brakes can be bought at any part store for the B body
make sure you tell DR Diff what backing plates you are using as the axle off set for the A body and B body brakes are different...
