Hello, looking for backing plates from an Olds rear that uses 5x5 rims and has the 3.07 register for the axle. I understand they were used from the early 60's to 85. I am not an Olds guy, so my parts history is weak. Any help is appreciated.

I need backing plates that the drums, shoes, brake cylinders are still available.

email at bteffeau@yahoo.com thanks
