This is my story hope it helps . i have just been through the ringer same thing as you , i bought my GTR 1990 in Queensland through a private seller , took it to Regency for an ID check , the blue plate does not mean shit in S.A they still do this in system in Queensland mine was done 6 months ago , In Queensland the minimum requirement is seatbelts hence the mod plate which will pass the vehicle inspection which is done by a local certified mechanic for RWC lol. At regency they told me to get an," exemption from compliance form" same as you , which was eventually sent to me describing in detail what works had to be carried out before i could send it in for a full inspection - crap. luckily for me my car was so stock it was running totally OEM . ,. Anyway my troubles started when i found out none of the Australian Design Rules had been carried out in Queensland - seat belts only , which means i had to carry out ADRs myself - side intrusion bars , child restraints (bullshit) , high mount stop light , leaded fuel restrictor (wank) because no one sells leaded anymore , list goes on and on and on , so im thinking how the f.... do i fix all this myself . Did what i could on the list and then got in contact with a guy on main north east rd to carry out the rest of the work , went to alot of trouble to find someone to comply my car , PM if you want his name and number as this guy is a legend does great ADR work good prices also sends it through regency himself ! Cost me $2500 includes inspection cost ,but he did heaps of quality work and that was with a stock car . I tried getting the left over rego money back in Queensland , but was totally f...kd around , they told me i would have to pay stamp duty again in Queensland and fill out a new customer form WTF ! i gave up .i wish i kept the plates . I hope the ADRs are done already unlike my car , but dont panic until you get that exemption form listing all work reqiured on your car, and then panic .My car eventually was passed after my compliance guy took the car 3 times to regency inspection all in the same day after ball joints failed , wheel allignment failed , If you fail to pass the same day its another 300 bucks , compliance guy took all the stress out for me - legend ! Any questions Pm .
