Willys 4X4 PickupVery subtle exterior changes were made to Willys trucks during their 1947-1965 production run so nailing down the exact model year can be tough. Let's add up the clues on this burly 1-ton 4X4 pickup. The two-piece windshield was used until a one-piece replacement arrived in 1960. The small rear window tells us the cab was built before 1954 - when larger cab-width glass was added. But it's the grille that tells us this one's a '50-'53 model. Though the bottom horizontal bar has gone missing on this example, this prow-shaped five-bar grille was used from 1950 to 1953. From 1954 onward, a simpler three-bar grille was used.
