Square headlight set ups don't come up very often (although it seems you can now buy the repro grilles through ebay).

If your really that keen I'd at least be asking the seller if they'd allow for a courier pickup if you organised it. Otherwise you'll probably have to either patiently wait and see if another one comes up or organise a holiday to South Africa

I remember another member on here awhile ago searching for the square grille setup....not sure if he ever found one or not.

Anyway good luck
