I suggest you get on the internet and look for used parts suppliers in New Zealand. We have one of the highest percentages of Japanese vehicles in the English-speaking world, and parts are cheap and easily sourced. For a small part, you could have it in less than a week, and the price including postage would be attractive, given the exchange rate of nearly 2:1 in your favour. megaparts.co.nz/mitsubishi-parts.php or kempys.co.nz
Both of these with the usual three w in front.

Do you think I didn't try there!

They all state that they fit but they dont. The small print usually says "for hook arms" So they do fit the passenger side or the rear screen as they are hooks but the 26" drivers side is not a hook and all the adapters (screw type) do not have their holes in the correct location. even the "Japanese adaptor kits" do not fit

Looks like it will be a NZ part.
