Berry Motor Group in Melbourne stock good replacement front indicator/parking corner light units, but you need to keep your existing globe holders (which are NLA new and hard to find now). They are superior to the dodgy Depo rubbish found on Ebay for about the same price and Berry's do fast delivery. New ones look sooo much nicer.
I replaced the rear tails on my NA 945 with units from Ebay which weren't that expensive (I had spare 745 ones but the plastic had aged and so they looked like crap). You'll need to re-use the gasket and the globe holders.
