SILLS FLOOR KIT COMPOSITE JEEP

Floor Sills Kit Composite

Set of 6 pieces

★ These sills are required when repairing corroded or damaged floor structures and must be welded in according to original body specifications.

Application

Application on Willys MB and Ford GPW vehicles from January 1944 until the end of production (October 1945 for MB, June 1945 for GPW), built with the ACM Type 2 composite body. The composite body was the result of standardisation between both manufacturers, with American Central Manufacturing producing the bodies for both Willys and Ford.

Installation notes

Installation requires welding and body work. The sills must be welded in at the correct positions beneath the floor panels, along the bottom of the side panels. It is essential that the correct position and angle are maintained to ensure proper fit of floor panels and floor plates. This is specialist work requiring knowledge of original construction and welding techniques. Consult body assembly diagrams or experienced restorers for exact mounting positions.

Compatibility

Please note: these sills are specific to the composite body period (1944-1945). Earlier Willys MB vehicles (November 1941 - December 1943) with ACM Type 1 body and Ford GPW vehicles with Ford-produced body (1942-August 1943) have different sill configurations. Check using the serial number or body characteristics (toeboard gussets, tool box recesses) which body type your vehicle has before ordering.

Historical context

The composite body was introduced in January 1944 as a standardised design for both Willys MB and Ford GPW production. American Central Manufacturing, which had already been producing bodies since the first Willys MA, developed this ACM Type 2 design combining features from both manufacturers to increase production efficiency during the final war years.
