Scott, et.al.: Can I assume that the car in question, being a "Federal" car, would only have to be brought to "Federal" spec's using "Federal" equipment?
Yes, as long as it is a "used" car. Being 31 years old, I doubt there will be any problem on that point! :laugh:
And as I mentioned before, things have changed a lot since the CA smog test now involves running the car on a dyno. My experience has been that they are a lot less picky on the visual inspection (to the point that I'm not sure they do any physical inspection at all
) than they used to be.
But of course pretty much all the major components have to be in place and operating to pass the tailpipe test. You might get away with the air pump not working, as long as the cat lights off, but I sure wouldn't want to bet on it. And the sniffer is plenty sensitive enough to notice an EGR valve or catalyst that isn't doing it's job.
Anti-runon doesn't affect emissions, so not required. They might notice if the hot air intake (thermactor) is missing, but I doubt it.
I don't know how much information is in the Haynes, especially on the later (after 1975) emission setups. But all this stuff bolts or clamps on, so I think doing the physical work should be no problem. Exhausts are always a hassle just because things tend to be corroded together and you have to work under the car (ramps or jack stands are required) with crud falling in your face. Personally, I'd take it to a shop to have the exhaust done. (I'd be happy to recommend the shop I use, but it's a bit of a drive for you.)
The hardest part will be collecting and identifying all the bits you need. You might need to buy a few special tools, like the gizmo for adjusting the mixture on the later ZS carbs, but not too many. This is not something I'd expect to complete in a weekend, nor maybe even two, but I believe it should be do-able if you have at least a modicum of mechanical ability.
We'll be happy to tell you more than you ever wanted to know about any particular part, but you'll have to ask the question first. Poke around on the Moss website, it has illustrations of most of them (if you can find the right page). Eg,

When you do get it assembled, go to the smog shop and specifically ask for a "pre-test". This is a mode where they can run through the entire test, but without sending the results to the state. That way if it fails (including missing parts), the state computer will not brand you as a "modified" or "gross polluter" car. The shop I use charges about $40 for a pre-test, $60 for a full test, so the total bill would be $100. But he is an absolute wizard at getting them to pass. He even managed to pass my 1980 Chevy, after all the pellets had fallen out of the converter!
