No, actually….not all are the same. The only difference I found is the 1984 and later rigs, albeit 11” or 13”, have a different e-brake connection at the brake drum backing plate. The earlier ones have a two bolt fastening method at the brake drum backing plate while the later have are a push in design. The good news is the Bendix backing plates are very universal in that a backing plate from a 9.5” semi-float POS axle with 13 x 2 brakes is the same as the backing plate for 13 x 3.5 on the big 10.5” full-floaters.
In my next situation where I will be putting a ’78 10.5” axle in an ’89 Suburban I must use the ’89 Suburban’s 9.5” axles backing plates on the 10.5” axle in order to use the later design park brake cables. YES…….Confusing, I know! Since I run manual transmission is almost everything I own a park brake is a must!
Got to love GM for their consistency in parts interchangeability though! Just figuring out the correct concoction of parts to make it all work is fun part.
