HRH, the D21 Hardbody shape that you have known as the only D21 front, we had the Navara (white one pic d) above as I think the 1986-1990 D21 and this was Badged as a Datsun Or Datsun Nissan or Nissan (feels like they got a bit confused, because I am right now?!)then, from 1990-1997 we had the Hardbody D21.
There are some earlier Hardbody fronts so it was that here from 1987 on, but they are not as common, seems like Nissan we're trying to flood the market, and New Zealand got the multiple badgings under the 2 Manufacturers namesas they were released elsewhere around the world.
