I think it depends on where. I can't even find simple parts at the OReilly's and AutoZone around here, not even at Napa. Baxter has stuff but they're smaller and limited. Most of the stuff around here is more focused on Import cars, and mainstream late models.
I had to special order parts for my truck here, which is crazy considering how common they are.
