Driver seat frame early Willys MB
For vehicles with small fuel cap
Left front seat frame (driver's side) for early Willys MB models and slat grille Ford GPW. This frame is characterised by the 'small mouth' opening in the floor plate, specifically designed for access to the narrow fuel filler cap (2 inch) used on the first production models up to approx. serial number 118,599.

Features
- Specific design for early models with narrow fuel cap (2 inch)
- Open-worked floor plate ('small mouth') for access to fuel filler opening
- Rolled steel construction for structural load capacity
- Mounting points on body floor
- Original specification for slat grille and early pressed grille models
★ Reproduction to original specifications for early WWII jeeps. Essential difference from late frames: the open-worked floor plate allows fuel filling without seat removal.
Application
Willys MB early production (approx. 1941-1942) and Ford GPW slat grille models fitted with the narrow fuel filler cap of 2 inch diameter. Later production (from approx. serial number 118,599) switched to a wider fuel cap with different frame design.
Installation notes
Frame mounts directly to the floor plate with mounting bolts and caged nuts. The open-worked 'small mouth' section must be positioned exactly above the fuel filler opening. Check before fitting that your vehicle has the narrow fuel cap (2 inch) — this frame does not fit vehicles with the later wide fuel cap.
Compatibility
Does NOT fit late MB/GPW models with wider fuel cap. Does NOT fit M38, CJ-2A, CJ-3A — these have different seat mounting systems. Only suitable for early WWII jeeps with original narrow fuel filler cap. If in doubt: check diameter of your fuel cap (small = 2 inch / approx. 50 mm).
Historical context
The early Willys MB and slat grille Ford GPW used a narrow fuel cap of 2 inch diameter, identical to that of later civilian CJ-2A models. From mid-1942, a switch was made to a wider filler opening, which necessitated a modified seat frame design to maintain access to the tank.
