Please check notes in each part listing to ensure the Roof-Rail Seal is correct for your 1977 OLDSMOBILE CUTLASS SUPREME with a 6.6L 403 engine. Special restrictions like "California only" or "with sport package" may indicate a Roof-Rail Seal fits only certain 1977 OLDSMOBILE CUTLASS SUPREME models.

Clicking a "More Info" link will display a picture and/or other details about that Roof-Rail Seal in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Roof-Rail Seal, 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 OLDSMOBILE CUTLASS SUPREME 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 1977 OLDSMOBILE will not be lost if you switch.
