Cut out a couple of discs from some 1/8 scrap metal I had laying around. Welded them in the backing plates. Carefully measured to find the center and drilled holes in the middle. I had this medieval tool left over from 20 years ago (part of an epic failure of an attempt to bore out a holley base plate).


After a couple of rotations, it was clear that the cutter was made for wood or aluminum, but it did give me a pretty clear mark for where to cut the new hole. So, I cut it out with a sabre saw. Tried to keep it inside the line as best I could. Cleaned it up with a die grinder.

I didn't worry about grinding the whole weld down. I did make sure I ground it down where the the new bolt holes will go, and the mounting nuts will seat.

Still have to drag the 12 bolt up to the bench, pull the axles, remove the old backing plates and fit these. Figured I won’t drill the bolt holes until I have it clamped on the axle housing to make sure I get them in the correct position.
Have ordered new shoes, wheel cyl and hardware.

Will post pics when I get them fitted.
