AZ emissions is -easy-. My '70 failed exactly once, because for some reason, the idle mixture screws were turned to full rich, so of course it blew high on idle. Turned them to full lean (it didn't run any different!) and went right through later that day, passed with flying colors.
There is no visual inspection of anything on a '70 other than the gas cap. They have never once popped the hood on my truck there. It's a simple constant-speed-load, then idle test.
The only car I've ever had fail AZ emissions is my girlfriend's '79 280ZX, which has sat more or less for over a year, and refuses to run right.
