Thanks Blake, exactly what I was after.
Ossietim; If your after this exact set I can put you onto the sell? Other wise, There are quite a few options for USA to AUS shipping. Basically any company that brings in cars will freight over parts for you. Although its pricey, expect about $400ish for a pair of seats. Gov has got a bit fee happy if the importers I've spoken to are to be believed. Plus you have to add postage to CA or WA with in USA on top of that. I've heard good things about eastcoast mustangs, I'd probably go with them unless they quoted really hi prices.
OH one last thing, on seats (or most anything you import) if its new, not used (has to be a verified 'new' seller, IE jeggs, summit etc. ebay is a no go even if the item is new), you'll save a fair chunk of cash on fees. On seats its about $140-160!
I really want buckets, but I think if I can sort out my bench seat rail, I'll just use that for a year or so as it's got a new skin already and is good to go in.
