Truck Sun Visor, Part 2233288
Very few of these external sun visor where ever produced. Rumor has it that this GM GMC truck sun visor is almost very simular to the Pontiac sun visor since they where both produced at the same plant. It is still a mistery as to exactly what year this visor was introduced. Since GM produced the Chevrolet sun visor, part number 986877, was not introduced until 1953. In 1954, the Chevrolet sun visor, part number 986936, changed to accommodate the one-piece windshield.
According to some accessory manuals, this GMC visor was available in 1951 but is still unknown as to the exact year. This illustration suggests otherwise, which was taken from an accessory manual. Since this truck has no vent windows & has pull-down door handles, which suggests that this visor may have been available in the late 40's.
