Personally I don't like "club registration" because I don't really like to get into club politics.
I also despise the ugly historic number plates. But putting that aside. What if you were to have say a FC Holden 100% stock to look at yet if legally fitted with a 186 Red motor with triple down draft strombergs and extractors that was approved with an engineers report. Would that qualify? If that does, what then of the same car with widened steel wheels and low back bucket seats that have also been approved and are part of the engineers report?
