Jeep: Need an ID on this “Willys” frame

[asianairborne]

Is this frame an original military model? The serial is ground off on the forward left side (Ford side). My understanding is that the body is a correct late war Ford. Thanks.

Hard to say from the pics, but the tub mounts on the driver side on an MB are in-board, on the CJ2A they are out-board (MB has part of the gas tank next to the fame here), the rear shock mounts on the CJ2A frame are farther forward, the battery tray is different, and lastly the front crossmember on a CJ2A has the mount for the steering bellcrank, the MB mount is on the front axle.

 

The last point might be easiest to check. This was to remedy a design flaw which caused an MB/GPW to steer to the left when braking hard due to the whole axle pivoting slightly forward then.
