Please check notes in each part listing to ensure the Power Steering Pump is correct for your 1978 GMC C25 PICKUP with a 4.8L 292 1BBL OHV engine. A-1 CARDONE & ACDELCO are competing brands, and each brand's Power Steering Pump may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Power Steering Pump fits only certain 1978 GMC C25 PICKUP models.
Clicking a "More Info" link will display a picture and/or other details about that Power Steering Pump in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Power Steering Pump, 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 Steering parts, other GMC C25 PICKUP 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.
