This 1959-1964 Chevy Impala RIGHT Rear Drum Brake Backing Plate is an original GM part that has been media blasted and primed. The way to distinguish between right and left is the whole where the emergency brake cable enters. It should face toward the front of the vehicle. Some backing plates may have pitting. Also, some backing plates had the splash guard during these years, but not all of them. Please indicate if you wish to have the splash guard with your backing plate.
