Thanks for all the help and suggestions so far !

The local RTA is of no help whatsoever and referred me to the Technical Info line so I have now written to the RTA Technical Manager as suggested.

Have also contacted 3 engineers so far - 1 has quoted $800   and the other 2 have not returned my calls. I will keep u all informed. It maybe easier if I move to Qld or ACT !  

Dear Forum
I have recently purchased the wonderfully and lovingly  restored "Effie C" from John Mayberry in ACT. The car is currently registered in ACT and originally registered in Qld. I now wish to register the car in Sydney and am now being asked to provide engineering certification for the mods already carried out to the car in spite of it being already currently registered and previously certified in Qld. As I am new to this process and this forum I would appreciate any help, advice and/or contacts that maybe able to assist me in navigating my way thru the maze.
Many thanks
Ian
