MPC 6347 - 1975 Datsun Monster Truck - 1979 release

In February 1972, the Datsun 620 truck was released and was in production until 1979. It was a regular cab truck (a longer "King Cab" version was released in 1977) and two wheelbases were offered, for a total of six different models. There was also a delivery van version, offered only in Japan. Naturally there were bare chassis models, and many importers installed locally made flat decks. There was also the U620, which is a crew cab "Utility" version. It uses a shorter, fully integrated bed to allow comfortably seating four people. The U620 was essentially a 620 pickup from the doors forward, with the bed and rear end being the only difference. Nissan continued the strong rhythms and styling of its previous vehicles, with a shoulder "wing line" or "Bullet Side" accent running alongside the vehicle. In most of the world the 620 was equipped with the J15, producing a claimed 77 hp (57 kW) and a claimed top speed of 135 km/h (84 mph).[5] A 2.2 liter diesel engine with 66 hp (49 kW) was later made available in many markets.

The 620 was also the first Datsun pickup truck to be available with a longer "King Cab" passenger compartment (called "Custom" in Japan). This used the bed from the normal 620 truck, but has a cabin stretched by 24 cm (10 in), all placed on the longer wheelbase.

The 620 was redesigned slightly for 1978, with changes to grille and front bumper. The suspension was also revised, increasing track at both ends by 30 mm (1.2 in). This also marked a name change in South Africa, where it had been sold simply as the Datsun one-ton pick-up, to "Datsun 680". A four-door crew cab variant was also offered in some markets.
