Keep using the words "kit car", "special constructed", "1965 Cobra," "Replica" and "Collector Car." Arizona will license the auto for what it looks like. You should also have "Collector Car" insurance to show them. You will end up with a 1965 vehicle and next to no plate fees. ($18.50 per year). Now is the time to look for a vanity plate. ($25 per year.)
Way back when I registered mine I simply shut up and let them decide everything.
