Welcome.
The older Toyota's going back to the late '70's(few car lines as well) are still popular hear, and in large populated areas, the wrecking yards(self service) are picked fairly clean, however the non self service yards can usually locate you any part you need, for a price.
Clean unmodified 4x4's here in California usually sell for $2500-5k for '79-'95 models. The design of the older gens has held up well over the last 3 decades, which keeps them popular.
