Hello -
This fellow:
http://www.piner.com/japco/ purports to have fiberglass flares and such for the 1200, but the photo links on the site are broken.
Perhaps he'd be willing to sell you the molds, if he doesn't have a lot of demand. I tried to find his place last time I was in NC, USA, but had
trouble locating him.
Don't know how well the parts would travel to NSW...
Good luck in your hunting...
