Please check notes in each part listing to ensure the Floor Pan is correct for your 1966 CHEVROLET IMPALA with a 4.6L 283 engine. Special restrictions like "California only" or "with sport package" may indicate a Floor Pan fits only certain 1966 CHEVROLET IMPALA models.

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

After choosing a Floor Pan, 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 CHEVROLET IMPALA 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 1966 CHEVROLET will not be lost if you switch.
