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.
