Floor Pans & Supports

Tom's Offroad carries both full floor pan replacements and targeted patch panels for the 1966–1977 early Bronco. Full floor replacements cover the entire cab floor in a single assembled panel for maximum rust repair, while patch panels address specific rusted sections without removing the full floor. Both options are available in steel matching the factory gauge for proper welding compatibility.

Replacing early Bronco floor pans involves removing the interior, seat, and carpet, cutting out the rusted section with a cut-off wheel or plasma cutter, cleaning the cross supports and rocker flanges, fitting the new panel, and welding it in with a MIG welder and roset welds or spot welds. Coat all bare metal surfaces with epoxy primer before reinstalling the interior.

Pull back the carpet or floor mat and probe the floor pan with a screwdriver or pick tool in any areas that look stained, feel soft, or show visible rust bubbling through the surface. If the pick tool penetrates the metal with light pressure, the panel is too far gone for surface treatment and needs replacement. Soft floor pans are a structural concern and should be addressed before the truck is driven.

Yes, if the rust is isolated to a specific area, patch panels are a cost-effective alternative to replacing the entire floor. Cut the patch to overlap the solid metal by at least an inch on all sides, weld the perimeter with full seam welds, and treat the back side with weld-through primer before installation. Patch repairs done correctly are as structurally sound as full replacements.

After installing new floor pans, coat the underside with a rubberized undercoating or an epoxy-based rust encapsulator before reinstalling any insulation or carpet. From inside the cab, apply sound deadening over the bare metal before layering in new carpet. Keep the drain plugs clear of debris, and address any water leaks at the doors, windshield, or top seals promptly to prevent moisture from accumulating under the floor covering.
