Does anyone have the emission requirements for a 1974 4X4, 350 cid? Trying to figure out all the emission before having it tested.

Thanks guys.

Did they have emissions back then on trucks, other than a PCV valve?

What about canister and hoses, that is what I need to know. Az is very picky with this stuff.

I don't think '74 had any emissions equipment outside of california.
