I would just advertse it as alfa romeo cam cover, originally for spica/smog.
I kinda think the smog pump stuff was CA only, but I may well be wrong....
I can see it has the rear brace, and I'm fairly sure it must have the two small bolt holes at front.
I once owned a 1976 "49 States" Spider that had and air pump on the left side of the engine. I recall there were some tubes from the pump to the exhaust manifold. Is that the same as a smog pump? The first mechanic I took it to cut the drive belt as I recall.
psssst....Clips were to hold warm air tube from exhaust manifold to the front of the spica airbox. All spica cars had them from 75 to 81.
Yeah. I know. But they were ugly.psssst....1981...1979
