Please check notes in each part listing to ensure the Weatherstrip Kit is correct for your 1978 GMC G35 VAN RALLY with a 6.6L 400 4BBL engine. Special restrictions like "California only" or "with sport package" may indicate a Weatherstrip Kit fits only certain 1978 GMC G35 VAN RALLY models.
Clicking a "More Info" link will display a picture and/or other details about that Weatherstrip Kit in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Weatherstrip Kit, 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 Body-Exterior parts, other GMC G35 VAN RALLY 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.
