What fits 73-76 A body disc brake backing plate ?

Thanks , Guess I'll order them tonight..........
The color is a Chrysler color :)
A 2002 Ruby Red Pearl. I saw a 68 Hemi Cuda from Indy painted that color and I liked it enough to have it put on mine . I really wanted a paint called O Sexy Red , Its a pearl paint that has tons of "flop" in in , but my painter said for a street car to stay away from it because its $$$$$$$$$$$$$$ to touch up or blend a panel back in.
This color looks good , and its close to the O Sexy Red , but O Sexy Red is in a whole other league
Thanks guys
