My 2 cents worth... This issue was raised some time ago in QLD with initial discussion and meetings held.... I believe if my memory serves me true that we had representations from DRB (Pete R), RCR (Craig W), Venom (Scott H), Snakebite (Don P) plus a fair few others who met to discuss. Sorry can;t remeber them all. By the end of the meeting we had more ?'s than answers and no clear outline going forward and I don't believe another meeting was held.
Having said that recently in QLD a 32 Roadster (I think) with a reverse sprung beam axle and a blown 460 Big Block passed rego!
Go figure....
