The Datsun 180B was also known in some countries as the 610 Bluebird, it was built from 1971-77, it replaced the 510, the 610 got the new coke bottle shape.
The 610 received a facelift in 1974, with prominent turn signals mounted on the front corners and with a more squared off grille, along with other changes.
In Australia, Datsun released the locally-produced 180B in 1972 as a 4 door sedan in Deluxe and GL trims, and a 2 door SSS coupe. Over the base Deluxe, GL models added a vinyl roof and upgraded interior upholstery and trim. The fully imported luxury GX was available from 1974. The SSS got twin carbys and miscellaneous sport options.
