According to the '72 sales brochure the colors available are; Wimbledon White, Mallard Green, Seapine Green metalic, winter green, calypso coral, candyapple red, royal maroon, prairie yellow, tampico yellow, swiss aqua, wind blue, bahama blue, bay roc blue metallic, sequoia brown metallic, chrome yellow, pure white. There are 3 different ways the truck can be painted two-tone; the roof a different color from the rest of the truck, the bottom of the body different from the top, and the bottom and roof different than the top. The brochure doesn't list all the color combinations but say there are 138 different ways the Styleside models can be painted.
Take a look at the Sport Custom in my gallery...it's tampico yellow and sequoia brown metalic.
