OK, I am making a few assumptions here, but looking on Google, the front end of the D21 Navara, looks almost identical to our WD21.
The wd21 front is exactly 5 foot wide, and the wings go straight back, where as the T2 Mk3 is 5 foot 4 inches wide, from the outside edge of the indicators on the wing and then the wings actually get wider heading back to the wheel arches...
So to be honest, I think you would be taking a gamble that would not pay out.. Shame though, as I think it would look good.
