Gimmie a Brake HELP

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

What I know is what I see in the above pic. I agree with what You've got there spec-wise, but what I see is a piss-load more than 5/16" of exposed shoe, and the angle
is actually hiding more unseen. Me-thinks there is something like 2.5" backing plates on there...........If it was simply a matter of axle offset, there would be almost no
shoe visible because the "extra" surface beyond the inner lining edges would cover most of that 5/16"
