[Modena]

Hi Tony and welcome to the madness. As has been pointed out there are some kits which use all new components and no Jag bits. Second hand remains an option for donor parts, while some new parts are built by the supplier (eg front A-arms).

Sidepipes are legal in Vic but will require heatshields. Getting them quiet enough to pass the test is another discussion entirely......

I'm not sure what you mean by not allowing tube space frame chassis? Classic Revival's are tubular space frame and they are being registered fine.

Enjoy your stay!
