Please check notes in each part listing to ensure the Brake Backing Plate is correct for your 1978 GMC CABALLERO with a 5.0L 305 2BBL engine. Special restrictions like "California only" or "with sport package" may indicate a Brake Backing Plate fits only certain 1978 GMC CABALLERO models.
Clicking a "More Info" link will display a picture and/or other details about that Brake Backing Plate in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Brake Backing Plate, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button, or click on "Find More Parts", to find more Brake/Wheel Hub parts, other GMC CABALLERO parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 1978 GMC will not be lost if you switch.
