1965 Datsun 320 Truck
.
 
 

The 1965 version of the Datsun 320 went into production in August 1964.
 The 1965 Datsun 320 was the fourth and final version of the 320 line. As with the previous models the only significant change to the exterior of the vehicle was to the grille. The 1964 model 320 had a wide grille that incorporated rectangular front indicators into the grille design. For 1965 the grille was again a full width design that incorporated the indicators, but now the design of the indicators has changed and they have gone back to using the same round indicators used on the 1962 and 1963 model 320s. The new grille is similar in design to the one used on the last of the Datsun Bluebird 312 series sedans and has four slots at the top and a series of three horizontal bars and four vertical bars.
 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.
 Most 1965 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. Some late 1965 models have the E-1 Mark 4 engines stamped from 547144 onwards. These have the oil pressure relief valve located on the oil filter housing. The other significant change was that for the 1965 model an optional 4 speed floor change gearbox was also available as well as the column change box.
 The production run of the right hand drive Datsun 320 ended in May 1965, when it was replaced with the all new Datsun 520 series. For some reason the left hand drive version seems to have continued in production for several months longer.

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.
