SMOG - where built and where sold

I have a 67 Olds 442 with AIR. It was built in Fremont CA and sold at a California dealer so it had to have smog equipment. It is pretty unique at car shows here in Texas.
If it was going to be shipped to a dealer out of California, the exhaust manifolds would have been plugged and no AIR even though it would have been built in California.
I once saw a 66 Caprice with a 396 equipped with AIR. Good ole California smog rules.
I have been in the mechanic field all of my life. I remember looking up emission specs for cars in the 60s and seventies and there were 2 categories; California and 49 states.
