A saginaw steering box and updated steering column have been added.

“This is a WWII Willy’s MB. It runs and drives. Original 4 cylinder flathead motor with three speed manual transmission. 4×4 with low and high 2 wheel and 4 wheel drive. The steering has been changed to a Saginaw box from the worm gear. Great project for restoration or 4×4 toy. Clean title.”
Tub rear and sides look very smoothed out (no seams or holes): bondo? fiberglass?
Looks to be a post war engine block.
