The 1973-1991 Chevy Truck Right Hand Inner Rocker Panel Backing Plate is a vital reinforcement component for restoring strength and stability to the passenger-side cab floor and rocker structure. Designed to sit behind the outer rocker panel, this heavy-gauge stamped steel plate supports one of the most rust-prone areas on squarebody GM trucks. Engineered to match original factory dimensions, it ensures a secure fit and integrates seamlessly with surrounding panels. Ideal for structural repairs or full cab restorations, this panel helps maintain the integrity and safety of your classic pickup.
Installation:
Difficulty: 4/5 – Requires welding, cutting, and structural alignment.
Instructions: Remove the old or damaged backing plate and prep the surrounding area. Test fit the new panel and trim if necessary. Weld it securely behind the rocker panel using factory seam locations. Grind welds smooth, apply seam sealer, and finish with primer and undercoating to prevent future corrosion.
