Believe me, I have to do the annual ADEQ dance with my '77 K5 and '80 K20, both of which just escaped many requirements by GM tweaking the trucks ratings in those model years (esp. the K20).

Neither have EGR, cats, evap or smog pumps. Just make sure that PCV system is hooked up and functioning. The air cleaner is fine, but that breather off the valve cover = fail.

Good luck! It is a PITA having to go back if you fail the sniff test.

What about my 84 C2500? It was bought new in California but been in AZ since then. I bought it in 2019 and it had a broken EGR and that's it. Plugs in the manifolds, no tubes, or air pump. Had a canister but wasn't hooked up. Engine is an older 350, simple dual exhaust. I put a stock air cleaner on it and have a chrome breather in the valve cover. Currently living in Yavapai County but wanting to move to Tucson. Any help is greatly appreciated
