There used to be at least one company in Melbourne converting Holden and Falcon wagons to 4x4, using parts from Land Cruiser or Patrol. One of my nephews had one. Not a product I admired at all, but he was using it as a car with moderate success. These conversions were done in the late 1970s I believe. (I think the biggest problem was the long station-wagon rear overhang, which pretty much limited the vehicle to reasonably smooth tracks, not cross-country stuff.)
