Please check notes in each part listing to ensure the Exhaust Manifold is correct for your 1974 AMERICAN MOTORS JAVELIN with a 4.2L 258 engine. DORMAN & ATP are competing brands, and each brand's Exhaust Manifold may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Exhaust Manifold fits only certain 1974 AMERICAN MOTORS JAVELIN models.
Clicking a "More Info" link will display a picture and/or other details about that Exhaust Manifold in a separate window (you may need to turn off your pop-up-blocking software for this to work).
