Application
Suitable for all Willys MB and Ford GPW jeeps produced between 1941 and 1945. Fits both early and late production bodies, including ACM Type 1 and Type 2 bodies. Note: GPW and MB have different rear seat pans but share the same rear floor panel between wheel arches and rear panel.
Installation notes
Fitting requires removal of the old panel by drilling out the spot welds (preferably use an 8mm spot weld drill bit). The new panel is positioned and spot welded to the side panels, wheel arches and the front floor panel. Ensure correct alignment of the floor riser which forms the transition between front and rear floor. Recommended: have fitted by an experienced body repairer.
Compatibility
Compatible with both Willys MB and Ford GPW. Note: this concerns the main rear floor panel — the rear seat pan itself differs between MB (inside frame) and GPW (outside frame) but is a separate component. Suitable for all production years 1941-1945.
Historical context
The rear floor panel formed a crucial structural component of the jeep body and was subject to corrosion from mud, water and salt damage during the war years. Modern replacement panels are manufactured according to the original American Ordnance drawings.
