Electrical stuff, like the bulb sockets, the steering column crush spacers, studs and star washers (which are not the easiest to find if you need them).

I've found so many usable parts on my 86 5th Ave, that I can't afford to take it to the scrap yard. I'd get maybe $120, but I pull $5- $10 in fasteners and connectors alone every month!
Let's also not forget all the wiring harnesses that might not be useful in there entirety, but have all the correct colors and gauges of wire if you need to splice or build a harness from scratch.
