[2] The new chassis and suspension allowed for the cab to be mounted four inches lower,[3] meaning an even bigger transmission tunnel hump but also a more car-like ride.

The most obvious visual differences were that the twin headlights were now mounted side-by-side, and a new grille of a concave egg-crate design.

[4] The range was C-100 to C-130, the heavier duty versions of the B-series were not replaced as the C-series gross vehicle weight rating now only went from 4,200 to 8,800 lb (1,900 to 4,000 kg).

The light C900 was new for 1964: sitting on an extra short wheelbase of 107 in (2,720 mm), fitted with the Scout's four-cylinder, 152-4 engine producing 93.4 hp (70 kW) and with minimal equipment; it was designed to compete with low-cost import trucks which became briefly popular before the introduction of the Chicken Tax.

[9] For 1967 the four was replaced with International's 266 cu in (4.4 L) V8 engine producing 154.8 hp (115 kW), rather than the overworked four, and given the name 908B (6,531 built, followed by 3,656 908C for model year 1968).

While completely different in appearance and now looking very similar to the Scout, the resulting D series continued this naming convention until the 1971 Light Line pickups were introduced.
