We are working to restore a 1975 K20. rear brakes are shot and want to tear down to axle and replace all the brake parts. We cant seem to find a backing plate on line. The rear end is a 14 bolt full floater. We do not want to do a disc brake conversion. Parts store employees cant seem to find the backing plates. here are some pics of what we are trying to replace. Drums are 13" and are fastened to the hub with the lugs. We even tried LMC truck and they list all the brake parts but.... the backing plate. Any suggestions on where I can find these on line? Thank you.

Can't you just clean up the backing plates, they don't look very bad in the photos?

we might but once we get that far in... we kind of want to be sure we can reuse. one of the plates is rotted out on bottom 2" of the plate. dont have a pic of that one. When we got the truck their were no brake lines left. previous owner just used truck to plow and got by with front discs so we anticipate the worst. what is so odd is with all the part you can buy for these square bodies, this part seems tough to event price out.
