If one does not have factory cruise control, power brakes, or automatic, the three ports for those would be capped from the factory ! Some have fabricated a cover over the Weber from the factory air cleaner assembly. Mostly the numbers from the tailpipes are what they are concerned about, pretty ridiculous considering that there are very few older vehicles still on the road here, despite lack of rust.

I spend half the year in Yavapai County now so no emissions, so registered here. Yes, my '88 Cab Plus has AC, still R-12.

You could also later look into Arizona emissions exemption as a historical/classic vehicle as 25 years old.
