The 1973-1991 Chevy Truck Left Hand Cab Floor Support / Brace is a heavy-duty stamped steel panel designed to restore critical structure to the driver-side cab floor in your squarebody GM pickup. This brace connects the cab mount to the floor pan, providing essential reinforcement in a high-stress, rust-prone area. Formed to factory specifications, it ensures proper alignment and long-lasting support beneath the cab. Whether you're performing a partial floor repair or a full structural restoration, this panel helps maintain integrity and ride quality for decades to come.
Installation:
Difficulty: 4/5 – Requires cutting, welding, and precise structural alignment.
Instructions: Remove the old or rusted floor support. Clean and prepare surrounding metal surfaces. Test fit the new support and adjust if necessary. Weld into place using factory seams and mounting points. Grind welds smooth, apply seam sealer, and finish with primer and undercoating for long-term corrosion protection.
