Gimmie a Brake HELP

Yeah Yeah, I know, just the same looking at that pic I'd find a used drum & slip it on and see how much it's off. If it were close and You could lathe the edge back some at
least You could move the damn thing around while You find, bead-blast & paint/powdercoat the new stuff. I'm guessing w/o looking them up, but those axles use green
style bearings huh?

Yeah, if you “knew” you’d realize it’s not even going to be close.

The offset on the backing plates is different by a half inch. But it’s not in the right direction. The SBP plates are a 1/2” shallower than the BBP plates. And the BBP drums are 3/4” deeper. The BBP axle flange is only about 5/16” further out. So, how much are you going to turn off those brake drums?

Here’s your backing plate measurements
