It is my understand that here in Arizona Emission testing requirments are based on the year that a Replica's MSO shows. If it has not been titled before.If Titled before as if you bring a car in from another state and they have classified it as a 1965 or 1966 then it would be registered here as same as the State it was last titled in.Right now on new construction the Replica kit's MSO date would need to be 1988 or older this year and 1989 next year.And be insured as a "Classic" Even better if the MSO called it a 1965 or 1966.
In the same light you can't take a late model car and put an older High Performance Engine in it and use the engine age as the critera for the smog check it would be the age of the frame in this case not engine
