Zeb,
I have spent a lot of time over the last month reading all the material i can find including ADR's, RTA docs and whatever else i can find.
Let me start by saying (and no offence to anyone on here), the only person you should take advise from for making a decision is the RTA accredited engineer. They will be the only one that you can hold accountable for advise.
It appears that the same rules as ICV apply for imports, this may be of interest
http://www.rta.nsw.gov.au/registrati...e_nov_2007.pdf page 3 clause 5 says establish the date of manufacture to see which standards apply. I think that clause will be your friend. I dont know if this is still current or if you car will apply here, but thought i would post it any how.
Liam.
