Phil, David H. mentioned Deans Ram which is located in Adelaide. He brought his car over from England so was able to use the personal import aspect for requirements re rego. His car was engineered by a local who may be able to supply the engineering documents for your chassis.
I will be in Goulburn for the nats staying at the Central Hotel. If you want to catch up I will see Dean before we leave and see what help he can provide to help you. Unfortunately he wont be attending.
