This 1959-1960 Chevy Impala Hardtop Windshield A Pillar Trim Molding RIGHT/PASSENGER'S SIDE is an original GM part #4754431 that has been professionally polished to show condition. This molding ONLY fits the Impala Hardtop but NOT the Bel Air Hardtop. The distinguishing characteristic of the Impala and Bel Air Hardtop molding is that the top portion of the Bel Air molding has a closed end compared to the Impala which is open in order to connect with another molding that runs along the top of the door. GM made two different Impala Hardtop styles, one has a screw hole in the upper side portion (see photo) and the other does not. Technically they are interchangeable, but if you have a preference, please indicate.
