Rocker panels are vulnerable to impact damage, and exposure to water, snow, and road salt makes them predisposed to rust. Damaged rocker panels are not only unsightly; they can affect the entire structural integrity of your car. Renew the structural rigidity and strength of your 1964.5-66 Mustang Convertible with this complete Rocker Panel Assembly from Scott Drake. The inner and outer rockers now feature thicker steel construction and are spot welded together just like the original. Includes the quarter window frame bracket.
