The 1973-1991 Chevy Truck Left Hand Inner Rocker Panel Backing Plate is a structural reinforcement component designed to support the inner rocker area on squarebody GM trucks. Located behind the outer rocker, this backing plate provides added strength and stability to the cab floor and lower body, especially in rust-prone areas. Crafted from heavy-gauge stamped steel, it aligns with factory specifications for a precise fit and dependable performance. This piece is essential for any cab restoration or rust repair project where full structural integrity is required.
Installation:
Difficulty: 4/5 – Requires welding and structural alignment.
Instructions: Remove the rusted inner rocker panel or backing plate. Clean and prepare the surrounding metal. Test fit the new backing plate and trim if necessary. Weld securely into place along factory seams. Grind smooth, apply seam sealer, and finish with primer and undercoating to protect against corrosion.
