Yes in AZ my ‘76 and ‘78 are registered out of Phoenix area. Unfortunately I work in the oven but have a place in Prescott to escape this hell holeI believe this goes back to about 1990. AZ had a twenty rolling emissions in areas that required emissions. It then changed to a fixed date, moving it back to 1967. My 68 had been exempt for a couple of years and was required emissions again. Basing the date off of that.
