A rapid stream of changes and new model numbers followed in this early post-war area, as pre-war parts dried up and new designs were substituted.

The 2225 was succeeded by the 2125 at the end of July 1948; this seemingly retrograde step marked the return to the more ornate pre-war 17T grille.

The 5147 was succeeded two years later by the final 6147 model, which received the 25 PS (18 kW; 25 hp) D-10 version of the old sidevalve engine.

Introduced in August 1958, the G220 had a 1,000 kg (2,200 lb) payload and a 300 mm (12 in) longer wheelbase; there were also updated G221 and G222 models offered.

On the improved 221 model (October 1958), these were replaced by more conventionally placed units next to the grille as US regulations did not permit the original layout.

[15] Another development which resulted from exposure to the American market was a strengthened rear axle which was also capable of prolonged highway speeds.

[16] In 1958 the Datsun 220 (and a 210 sedan) was exhibited at the Los Angeles Auto Show, with American exports beginning soon after.

The 320 series underpinnings were largely inherited from the earlier 120/220, although with clear improvements and using body panels and overall design language of the new 310-series Bluebird.

All Datsun trucks kept the A-arm torsion bar front suspension with leaf-sprung rear ends and had a 1/2 ton load capacity.

Its back half is greatly different than that of the standard, separate bed 320 pick-up; it uses much of the rear sheet metal and the taillights from the V320 Light Van.

[citation needed] The 620 was also the first Datsun pickup truck to be available with a longer "King Cab" passenger compartment (called "Custom" in Japan).

This was a "50-state car", with an EGR system for pollution control which sufficed to meet California's stringent emissions standards without a catalytic converter.

[citation needed] As a result, the 620 was competing with the larger American pickup trucks, which in turn gave Datsun a strong reputation in the United States.

In Japan, round headlights were standard but higher-end models like the GL received square headlamps.

"NAPS" was the terminology Nissan used to describe their pollution control technology as a result of emission regulation laws having been enacted in Japan, starting in 1975.

It was a bare-bones truck that was only available as a regular cab with a 1.8 m (6 ft) bed, and was discontinued after 1982, although the 1983 model year did have the Hustler logo.

Unlike the GL, the MPG model of the Nissan 720 was a stripped-down version of the truck to improve fuel economy.

Unlike the others it had only a driver side mirror, single walled bed, vinyl bench seat, and other bare bone accommodations.

The 2WD deluxe model came with front bench seats of varying patterns to match the door trim and interior in blue, black or tan.

In addition, there were roll-bar and bumper-brush guard options for the 4WD variant that were installed by the dealership with mounting points for off-road and fog lights.

For the interior, this top-of-the-line model came with full carpeting, bucket seats, tachometer, quartz clock, intermittent wipers, center console, and woodgrain accents on the dash and door.

The 2WD and 4WD sport truck package came with factory air-conditioning as well as the clock and tachometer in the cluster as standard with exclusive gradient-patterned bucket seats for both drivetrains (with the 4WD versions offering the center console and gauges of the DX model, and the 2WD having center console storage in place of the transfer case lever), as well as King Cab variants.

Ironically, the ST package had no performance modifications, however in the 1986 model year it had an optional Z24i single-port fuel injected engine.

The interior was completely carpeted, and incorporated a rear folding bench seat similar to the first generation Toyota 4Runner.

[30] The United Kingdom only received the longer wheelbase, as a standard bed 1-tonner with the L18 engine or as the four-wheel drive 2.2-litre King Cab with 96 hp (72 kW; 97 PS).

The Nissan Pathfinder was derived from the hardbody truck and started in the same model year with chassis code WD21.

For North America, the Z24 was replaced for the 1990 model year by the KA24E of similar displacement: a SOHC engine of respectable performance.

[41] The V6 was no longer available in the US starting with the 1996 model year because Nissan was unable to meet the requirements of the new OBD-II emissions law in time.

These Hardbody small pickup trucks sold very well worldwide,[citation needed] and are still often seen both on-road and off-road.

[42] Production of this model in China dates back to 1992, when Sammitr, a vehicle assembler of Thai origin, established a joint venture subsidiary in Changchun China: Changchun Sammitr (Sanyou in Chinese) Motor Co. Ltd., to produce parts and accessories.
