As jrpontiac has mentioned, alot about this truck has me scratching my head. It has the Heavy Duty '39-'49 cab which uses double crank out windshields,(smaller medium duty COE cab has one piece, single split crank out windshield) Has Heavy Duty large stud, 10 lug wheels, which were used on the Heavy Duty axles. It has the grille of the smaller medium duty COE's, & has the smaller block engine with plugs on the passenger side, as the smaller medium duty COE's use. The Heavy Duty GMC COE's used a larger 6 cylinder engine with the plugs on the driver side. The larger Heavy Duty COE's also used a different style grille.
