1964 Datsun 320 Truck
.
 
 
The 1964 version of the Datsun 320 went into production in August 1963.
 The 1963 model Datsun 320 was the third update of the 320 line. Again the changes for the new year model were mainly to the grille design, but the new grille for the 1964 model actually required some significant modifications. The grilles on the previous two models were a narrow design, with a pair of round indicators set either side of the grille. The grille for the 1964 model 320 is substantially different to the other models. This new grille is much wider and now extends right out under the headlights. On this new grille the indicators are now housed inside the grille. The indicators are no longer round, but are instead an odd shape, basically a rectangle with one lower corner rounded off. Due mainly to the odd indicator shape, the 1964 model required new front guards with a different shape hole for the indicators. The only other major difference is that in the cabin from 1964 onwards there is a parcel shelf under the dash on the passenger side. The rest of the vehicle remained largely unchanged from the 1963 model.
 The badges are the same as the previous models, on the side say Datsun 1200, and a badge below that says 60hp, or 55ps on the Japanese domestic models. The badge on the bonnet says Datsun in an arc at the top and has a capital D in the middle. The bonnet badge on the Bluebird sedan is similar but instead of a capital D it has a sort of boomerang shape logo.
 1964 models have the E-1 Mark 3 engines with engine numbers from 280170 to 547143. These use a full-flow type lubrication system with a detachable alloy oil filter housing. The oil filter now faces upwards. Camshaft oil pump/distributor drive cog has 13 teeth. 6 Philips head screws hold down the tappet/valve cover.
 The 1964 model Datsun 320 was in production until August 1964, when it was replaced with the slightly updated 1965 model 320.

Model Variations
 
Datsun 320 
The 320 was the standard truck version. It's cabin section was seperate to the cargo section, with about an inch gap between the two. It has short doors. It was also available as a cab/chassis version without the steel cargo section, which allowed the buyer to fit his own body. 
Datsun N320 
The N320 was a 'styleside' body version of the 320. The N320 has a one piece body. The cabin and the cargo sections are joined together, there is no gap between them.  
The N320 has doors that are a couple of inches longer than the 320.  
The back of the roof has a different profile and is cut off more squarely than the 320. The gutter rail at the back of the roof is mounted high and is heavilly curved. The gutter is about two inches above the rear windscreen at it's highest point. 
Datsun U320 
The U320 is a 4 seat version of the N320 with a smaller cargo area. It has a one piece body, the cabin and the cargo sections are joined together, there is no gap between them.  
The U320 has doors that are a couple of inches longer than the 320.  
The front bench seat has a one piece base and a 2 piece backrest. Each side of the backrest hinges both forward and towards the middle to allow access to the rear seat.
Datsun V320 
The V320 is a light van version of the N320.  
The V320 was marketed as either a light van, a delivery van or as a heavy duty station wagon. It had seating for 5 people, but the reat bench seat would fold down to give it a full length flat cargo area.  
It was similar in appearance to the WP311/WP312 Datsun Bluebird Wagon of the same era. The Bluebird Wagon had 5 doors and was based on the lighter sedan chassis with double wishbone front suspension. The V320 was a 3 door that was based on the 320 chassis, giving it the same height adjustable torsion bar front suspension, and load carrying capacity, as the 320 Pickup. The ride quality and handling was not as good as the Bluebird Wagon though.  
The V320 has doors that are a couple of inches longer than the 320.  
The front bench seat has a one piece base and a 2 piece backrest. Each side of the backrest hinges both forward and towards the middle to allow access to the rear seat.
