I've ssen a 2 peice backing plate hangin on the wall at a checkers auto store.dont know how good they arte but the axle don't have to come out.Tom
I know which one you're taking about. Unfortunatly, they only make those for the '80s GM G body, F body, A body, and S-10 pickups/Blazers. Those all use the same backing plate, and have a corrosion issue, particularly around where the wheel cylinder mounts. I've installed them before, they're ok if you want to save time and labor. I'd use a 1 peice if I were to replace the ones in my Blazer, though.
