unfortunately guys, if you want your cars to be on the historic scheme, they basically cant be modified at all. and as far as i am aware, that includes brakes and suspension
its only normally where factory parts are no longer available that a suitable period replacement can be allowed
its not regency that you have to convince either, its the car club you join. they inspect it and issue a certificate to state that it meets the requirements, and as the whole club could lose its certification under the historic vehicle scheme (and therefore all the members will lose their historic status) they dont normally bend the rules for anyone.
basically, if you are considering historic reg, approach the car club you have in mind and have a chat to them about it. they will have someone there that is all up to date on the rules and can help you out (if the club is certified as a historic vehicle club with the registrar of motor vehicles). there is also a code of practice available for historic vehicles from here:
http://www.sa.gov.au/topics/transport-t ... d-vehiclesas well as codes of practice for left hand drive vehicles and street rod vehicles. dont get me started on the hipocrisy of historic vehicles having to be stock and street rod vehicles having to be modified for them to be eligible......
anyway, very nice cars anyway guys. whatever you decide to do with them i hope they bring you much happiness
