Please check notes in each part listing to ensure the Hanger / Insulator is correct for your 1973 PLYMOUTH VALIANT with a 3.7L 225 engine. Special restrictions like "California only" or "with sport package" may indicate a Hanger / Insulator fits only certain 1973 PLYMOUTH VALIANT models.
Clicking a "More Info" link will display a picture and/or other details about that Hanger / Insulator in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Hanger / Insulator, 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 "Find More Parts" to find more Exhaust parts, other PLYMOUTH VALIANT parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1973 PLYMOUTH will not be lost if you switch.
