A 1954 Chevy Taillight Backing Plate. These backing plates I offer are original GM Taillight Backing Plates that I purchase used. I have them media blasted then powder coated black. I chase the threads of the bolts or replace the bolts if needed. These are not reproduction so there should be no issues with fit and function. In other listings you will find the chrome taillight bezel, all the lenses, the reflectors and all parts needed to assemble a complete assembly. In a different listing you will find complete taillight assemblies already assembled with all reproduction parts.
One important point to understand in reference to 1953 versus 1954 Chevy Taillights. The rear fender area on the 1953 or 1954 Chevy where the taillight mounts is the same for both years. But the backing plate that the chrome bezel mounts on, is different on the 1953 and the 1954 Chevy. So to change the taillight assembly from 1953 to 1954 you need to replace all the lenses, chrome bezel and the backing plate.
