Went down this path a while back but didn't go thru with it. Was close to buying new from Summit Racing http://www.summitracing.com/parts/WVI-60-573404/All/ free freight to USAtoAUS depot in US and shipping to Aust via USAtoAUS.com $100 Aus for 4 wheels. When the Aussie $ was up around 93c US it was around $670.00 all up which looked like reasonable buying... assuming all went to plan...
