1964-88 Rear Drum Backing Plate – Rear Axle LH. We’ve made the reproduction to replace the following: GM #’s 18014440, 18014441, 5469279, 2620563, 2620564, 18002387, and 18002388 which use a left and right backing plate, not a universal style. This also features the brake shoe mounting stud pressed on like GM. This is the most correct reproduction on the market. This is for 9” rear brakes with cover. Fits most all GM cars with 10 or 12 bolt rear ends.
