Yeah just like most places. I've seen just about every normal part advertised as "GX" on eBay. This BW axle was probably used on the GX, but also on the Deluxe too i'm sure.

Datsun-Nissan South Africa made the 1200 GX up until 1975. With real twin carbs, 1972 grille and everything. It seems that these axles were manufactured locally in Johannesburg by the local Borg Warner division. Local hubcaps too, and Datsun 510 bumpers from the factory
