Do you have OEM CA emissions / smog equipment still in place?

Here's the tag from my '72 California 3/4 ton 4x4 Suburban. I have no reason to suspect the fender well has been replaced. The engine has been replaced along with the exhaust. PO installed headers/aluminum intake. No AIR brackets left.

A suburban is not considered a commercial vehicle like a truck is here. It would make sense that it would have AIR vs. a truck.
