What It Helps Repair

• Rust holes in the truck bed floor

Installation Notes and Tips

This panel uses weld-on mounting and should be installed by spot-welding over the damaged bed area. Surface preparation is important: remove loose rust, scale, and weakened metal before fitting the panel. After welding, finish the repair as needed and paint the panel if a color-matched appearance is desired. Confirm vehicle application by year, make, and model before installation.
