Hi Sciro and Welcome to the forums.
Thats a hard one, I recall a friend of a friend attempting to track one of these down. Your local wrecker might be the best bet but chances are they aren't going to have any or be any good if they do.
I think he ended up getting it from ASV although they aren't in NSW.
Another place I can think of which I have heard good reports about is
Fabtech Bodykits again these guys are in QLD from memory.
I know this isn't exactly what you are after but its worth a buzz to see what sort of price range your up against.
Cheers
Darren
