I don't see how that interpretation makes any sense back in the days of VIN numbers. because if I presented an 83 vin numbered car, didn't it have to be an 83 car? Not an 83 VIN car but built to an 84 car.

Or are you saying that as long as my vin number fell anywhere within the years and models on the spec line I could build it up and present it as any year and model on the spec line? Again, back in VIN days, could you really present a 1983 VIN numbered car and register for an event as an 84?
