In 1957, the grill changed to a more open design and the hood was given “spears” resembling the Bel Air.

In 1958 the series was renamed “Apache”, found on fender emblems, given a second set of headlights, and received other minor changes.

The cab is taller in size, and in-cab steps replaced the running boards of previous models.

A "step" between the cab and rear fender aided access to items inside the pickup bed.

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.

This was the last year that the NAPCO (Northwestern Auto Parts Company) "Powr-Pak" four-wheel drive conversion could be factory ordered.

The mid-1955 introduction of Chevrolet's Cameo Carrier pickup truck helped pave the way for the Fleetside.

The Cameo offered an array of car-like features that included passenger-car styling with rear fenders continuing the cab's body lines to the back of the truck, two-tone paint, a relatively luxurious interior, whitewall tires, a chromed grille/front bumper/special rear bumper, as well as an optional V8 engine, automatic transmission, and power assist steering.

[6] The outer fender skins were fiberglass, attached to a standard, step-side steel cargo box.

A standard tailgate was supported by retractable cables, with latches mounted inside the bed.

The multi-piece rear bumper featured a door that accesses a hidden spare tire carrier.

In 1957, a special version was made for GMC to be shown at national car shows called the Palomino,[7] which had a Pontiac 347 cu in (5.7 L) V8 installed, borrowed from the 1957 Star Chief.
