Redoing the rear brakes on the truck I just purchased. It has the 11 inch drums with 2.75 width shoes. Both backing plates are bent causing the rear brakes to constantly lock up. The backing plates are 11x2.75, OE part numbers are 357854 RH and 357853 LH. They have been discontinued and no aftermarket ones are available that I can find. Has anyone run into this and have any suggestions? Does anyone have some old ones lying around from a disk conversion they want to sell? I have a GM 10 bolt 8.5. None of the junk yards here have any. Thanks

I'm pretty sure it's the same story for front plates as well. Gotta find originals as far as I know.
