67 Dart 83/4 rear w/B Body Drums-69 Sport Satellite 11” what are the correct Brake shoes to use?
Did the rear brakes come as a matched set- backing plates, drums, etc?
11" rear brakes come in three widths, 11x2", 11x2.5", and 11x3". The backing plate offset for each one is different, so, you can't mix and match shoes and drums with backing plates. An 11x2" backing plate needs 11x2" shoes and drums, an 11x2.5" backing plate needs 11x2.5" shoes and drums, etc. The backing plate is unique to the set up. If you don't know which brake set the backing plates are for, you'll have to measure them.
To measure the backing plate offset you want to set the backing plate flat on a bench. You'll need to hang the bottom 1/3 of the backing plate off the edge of the bench so that the mounts for the e-brake cables don't keep the backing plate from sitting flat. It isn't much, but they do change the measurement. Then, measure from the bench to the top of the backing plate through the center hole (for the axle) in the backing plate.
If you get ~1.75", you have 11x2.5" plates. If you get ~1.5", you have 11x2" plates. Those I know for sure, as I've measured them. I don't have a set of 11x3" backing plates, but the math would say you'd get ~2" measuring them as I described above. This is because half of the additional width is on the inside of the axle flange and the other half is on the outside to keep the axle flange in the same spot, as there was only one axle offset for BBP 8 3/4 axles.
The other possibility is that Moser makes axles with the 5x4.5" bolt pattern that have a SBP flange offset. If you didn't specify that you wanted a BBP flange offset as well as the 5x4.5" bolt pattern, you may have SBP flange offset axles, which have to use redrilled SBP brakes.
