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.
