The 1960-1972 Chevy Truck Inner Rocker Panel Backing Plate is a heavy-duty steel reinforcement panel designed to restore structural support behind the driver or passenger-side rocker panel. Specifically engineered for classic GM trucks, this plate provides a critical foundation for maintaining cab integrity, especially in rust-prone areas. Stamped to match factory specifications, it fits cleanly behind the inner rocker and ties into the cab floor for improved strength. Perfect for frame-off restorations or targeted rust repair, this backing plate ensures long-lasting durability and safety for your vintage truck.
Installation:
Difficulty: 4/5 – Requires cutting, welding, and structural alignment.
Instructions: Remove the rusted inner rocker or existing backing plate. Clean and prep surrounding metal. Test fit the new panel and trim as needed. Weld into place along factory seams, ensuring solid contact with the floor and rocker. Grind welds smooth, apply seam sealer, and finish with primer and undercoating for long-lasting protection.
