Well for someone who needs it you might be able to name your price... I think you could easily get $100-$200 if it is a complete set up and someone was looking for it in CA.
For everyone else, it is just something to get rid of. Are you sure that your County will never require testing?
That's an excellent point. My '77 was originally sold in California, but was taken to Grand Junction, CO in the early '90s and didn't require smog testing.
But when I bought it, the stuff had been saved and was all put back on except for the cat. (And from what I understand, you're usually better off with a new one of those anyway, rather than experimenting with an old one, only to find that it's not working and has to be replaced anyway.)
Unless you're absolutely certain that you'll be keeping the Bronco for the rest of your life, and that it will never, ever need an inspection, you might be better off just putting it all away in a box somewhere rather than trying to sell it off for a few bucks.
