1962-1966

Although Chevrolet had produced a pickup truck since 1918, the use of the C/K nomenclature as the truck's name didn't begin until 1962 . Pickups were still offered in Fleetside (smooth-side) or Stepside (separate pontoon-style rear fenders with running boards or "steps") body styles. Corresponding GMC trucks were called either Wideside or Fenderside . Front-end design was revised from the previous 1960 and 1961 trucks, which had odd oval-shaped pods in the front of the hood containing the turn signals. The '62s had a lower, flatter hood that had the high-mounted turn signals more tastefully integrated. Large single headlights replaced the former dual units, and the grill contained nine horizontal slots. Several models were offered in both two- and four-wheel drive. The two-wheel-drive versions had the "C" prefix and came in the half-ton C10 and C15 (long bed), the three-quarter-ton C20 and the one-ton C30. Four-wheel-drive models had a "K" prefix and were called K10, K15 and K20. There was no four-wheel-drive version of the one-ton pickup and hence no K30. GMC models were called 1000/K1000, 1500/K1500 and 2500, with the K signifying four-wheel drive. Trim levels consisted simply of base and Custom. The Custom added an aluminum bodyside molding and cloth (versus vinyl) seating. Engine choices included the standard 236-cubic-inch inline six (with 135 horsepower), a 261-cubic-inch six-shooter with 150 horsepower and a 283-cubic-inch V8 with 160 horses.

In 1963 , a coil-spring front suspension replaced the former torsion bar setup and an egg-crate-style grill debuted. Two new engines appeared: a new base engine (a 230-cubic-inch inline six with 140 horsepower) and an optional 292-cubic-inch inline six with 165 ponies.

A new windshield and A-pillar design freshened the truck's looks for 1964, as did a new grill with a finer crosshatch texture. Inside the cab was a new dashboard with a revised instrument cluster.

Although the pickup's looks didn't change in 1965 , a few new options appeared. Air conditioning and a 327 V8 (with 220 horsepower) could now be ordered, making the pickups more powerful and more comfortable.

A bigger (250 c.i.) inline six with 155 horsepower became the new base engine for 1966.

1967-1972

A much more modern truck graced showrooms for 1967 as a complete restyle took place. A clean, broad-shouldered look was the main theme, and both Fleetside and Stepside body styles were again offered. A new Custom Sport model debuted, featuring bucket seats with a center console. Long-bed models no longer had a separate name; they were simply called long beds.

1968 brought side marker lights, a 307 V8 (which replaced the 283), a bit more chrome trim and a 50th anniversary edition that featured gold and white two-tone paint.

A new grill with a wider horizontal centerpiece and a foot-operated parking brake (which replaced the former hand brake) updated the pickup line for 1969 . A trio of new V8s became available this year; a pair of 350s with either 300 or 350 horsepower and a 396 with 310 ponies but more torque than the smaller V8s. GMC introduced a Super Custom model with slightly upgraded interior and exterior trim.

Changes for 1970 included a few new options such as a tilt steering wheel and a stereo with eight-track player. And, for the first time, the shiftless masses could operate the four-wheel-drive models thanks to the newly available three-speed automatic transmission.

A new egg-crate grill graced the front of the 1971 pickups. New trim level names debuted, including the base Custom, the mid-level Custom Deluxe (formerly the Custom) and the Cheyenne (formerly the Custom Sport Truck).

Interior refinements, such as molded door panels and an optional Highlander seat trim, took place for 1972 .
