As the successor to the venerable Advance Design trucks, the Task Force Series ran from late 1955 (second series) through 1959.

The 1955 second series offered standard options and add-ons such as 12-volt electrical systems, the first V8 (265 cubic inch), and fleet-side 6-foot, 7-foot, and 8-foot-length beds.

1955 Second Series Chevy Pickup Differences

1955 was the first year for new body style. New “wrap-around” windshield – a truck industry first and optional wrap-around rear window on Deluxe cabs. Power steering and power brakes are now available for the first time on GM trucks. The electrical system has been upgraded to 12 volts. Only year for 7-foot bed length. Fenders have single headlights and a one-piece emblem is mounted below the horizontal line on the fender.

1956 Chevy Pickup Differences

Wider hood emblem. Two-piece fender emblems are now mounted above the horizontal fender line. Last year for egg-crate grille.

1957 Chevy Pickup Differences

Only year for the more open grille. The food is flatter with two spears on top, similar to the 1957 Bel Air. Fender emblems are still above the fender line, but are now oval-shaped, as opposed to previous versions in the script font.

1958 Chevy Pickup Differences

The first year for fleetside beds. Received a significant redesign of the front end. All ⅓-ton trucks are now called Apaches. The truck now has four headlights instead of the previous two and features a shorter, wider grille running the width of the front end. Parking lights are now in the grille instead of being in the front of the fender and the hood is similar to the 1955/1956 models, but with a flat “valley” in the middle. The first year for factory-equipped air conditioning.

1959 Chevy Pickup Differences

Minimal changes from 1958, the most apparent was a larger and more ornate hood emblem and redesigned badging on the fenders. The last year that the NAPCO (Northwestern Auto Parts Company) “Power-Pak” four-wheel-drive conversion could be factory ordered.
