The 1968-1972 GM A-Body Rear Full Floor Pan Brace is a critical structural component that reinforces the rear floor section beneath the seat area. Designed to restore strength and stability to the underbody, this brace supports the rear of the floor pan and integrates with the inner rocker panels and rear seat mounts. Constructed from heavy-gauge stamped steel and engineered to match factory specifications, it ensures proper fit and long-term durability. Ideal for rust repair or full floor pan replacements, this brace is essential for restoring rigidity to your classic GM A-body coupe or sedan.
Installation:
Difficulty: 4/5 – Requires welding and careful underbody alignment.
Instructions: Remove the damaged or rusted original brace and prep the surrounding area. Test fit the new brace beneath the rear floor pan, aligning it with the factory weld locations and seat mount points. Weld securely into place, grind smooth, and apply seam sealer and undercoating for protection before reinstalling interior components.
