The 1973-1991 Chevy Truck Right Hand Cab Floor Support / Brace is a high-strength structural panel designed to reinforce the passenger-side cab floor and body mount area of your squarebody pickup. Made from heavy-gauge stamped steel, this support brace connects the cab mount to the floor pan, providing essential rigidity and long-term durability in one of the most corrosion-prone areas. Engineered to match factory specs, it installs cleanly beneath the floor and ties into adjacent panels, making it an ideal choice for restorations, patch repairs, or full structural rebuilds.
Installation:
Difficulty: 4/5 – Requires cutting, welding, and structural panel alignment.
Instructions: Remove the existing rusted or damaged floor support. Clean and prep the surrounding area. Test fit the new panel and trim as needed for proper alignment. Weld securely along original seams and mounting points. Grind welds, apply seam sealer, and finish with primer and undercoating to prevent corrosion and maintain long-term durability.
