69 Nova backing plate

[SS427]

Not a hard item to come up with and I believe Camaros, Chevelles and Novas all shared the same backing plates regardless of 10/12 bolt as long as the brake diameter is the same but I could be wrong or so Ann tells me from time to time.

Yours looks like it might have been caused by an original stamping flaw as there is no force on the pin to tear it out other than springs and they sure as hell cannot do that especially since it looks like it was torn towards the center carrier housing and not into the brake area. Weird.
