In 1955, Chevrolet retired its Advance series of pickup trucks and introduced the Task Force line. Sporting a new appearance and a variety of enhancements, the Task Force trucks evolved considerably between 1955 and 1958. In 1958, all Task Force trucks were dubbed the Chevrolet Apache, a name they would carry until the end of the series in 1959. There was little difference between the 1958 and 1959 Apache, although 1959 was the last year it was available with the Powr-Pak, four-wheel-drive conversion offered by the Northwestern Auto Parts Company.
