Hi Fellas. Iwas just lurkin around and come across this. Its a HJ75 built by a dealer in Queensland called Town and Country Toyota and I have their sales brochure somewhere.They are still in business but no longer convert Landcruisers. This one appears to have Northern Territory plates.
Most of them are 6x4 but they are still made by in Victoria and West Aust with a 6x6 option.
I also have this pic of one in better condition.
