The Chevrolet Task Force (or in some cases, Task-Force) is a light and medium-duty truck series by Chevrolet, their first major redesign since 1947. Its GMC counterpart was the Blue Chip series. It was billed as being more stylish compared to the earlier Advance Design Series while still maintaining its rugged durability. First available on March 25, 1955, these trucks were sold with various minor changes over the years until 1959, when the C/K Series trucks replaced the Task Force models for 1960. 1958: All light-duty trucks are now called "Apache", medium-duty trucks called "Viking", and heavy-duty trucks called "Spartan". First year for factory-equipped air conditioning. Significant redesign of front end, featuring a shorter/full-width grille, four headlights instead of the previous two, and Parking lights are now in the grille instead of being in the front of the fender. The hood is similar to 1955/1956 models, but with a flat "valley" in the middle. A new "styleside" all-steel bed replaces the Cameo/Suburban versions; called "Fleetside" by Chevrolet and "Wideside" by GMC, available in 6.5 ft (2.0 m) and 8 ft (2.4 m) lengths. For 1958, GM was promoting their fiftieth year of production, and introduced Anniversary models for each brand (Cadillac, Buick, Oldsmobile, Pontiac, and Chevrolet[5]); the trucks also received similar attention to appearance, but staying essentially durable, with minimal adornment. 1959: Minimal changes from 1958, the most apparent was a larger and more ornate hood emblem and redesigned badging on the fenders. This was the last year that the NAPCO (Northwestern Auto Parts Company) "Powr-Pak" four-wheel drive conversion could be factory ordered.
