The 1960-1966 Chevy Truck OE-Style Left or Right Cab Floor Support is a high-quality structural component designed to restore strength and stability beneath the cab floor of your classic GM truck. This support installs on either the driver or passenger side and ties the rocker panel, floor pan, and cab mount together, providing essential reinforcement in one of the most rust-prone areas of the body. Crafted from heavy-gauge stamped steel and formed to match factory specifications, this support is ideal for restorations, rust repairs, or cab replacements where safety and structure are paramount.
Installation:
Difficulty: 4/5 – Requires cutting, welding, and precise panel alignment.
Instructions: Remove the rusted or damaged floor support by cutting along original seams. Clean and prep the surrounding metal. Test fit the new support and trim as necessary. Weld into place along factory seams, ensuring it aligns with the rocker and floor structure. Grind welds smooth, apply seam sealer, and finish with primer and undercoating to protect against corrosion.
