You might try Dundee Auto Parts. They are a truck only junkyard in S.E. Ohio. When I lived in Ohio, I used to go there for parts and they always had quite a few Toyota trucks. It has been over ten years since I was there though, so I don't know what their inventory is like these days. The yard is HUGE and at least in the past, they let you wander around on your own. I couldn't find a website, but you should be able to find their number in the Yahoo yellow pages. They are in East Liverpool area.
