It says in your post that you live in CO. In Denver there is a salvage yard called the YotaYard. Nothing but older toyota stuff. You can try and bargain with them if you go in person, I haven't ordered or have something shipped from them so I don't know how that goes.

Good luck with your decision. Personally, I've always had luck finding parts for my rig. Usually, any auto store has what I want in stock.
