I've used car-part.com with some success over the years, but for sure ask a lot of questions to confirm it's the right part and get pics if you can as others have commented. Very few yards seem to list detailed info and even less update their listings when it's sold. I learned not to get my hopes up if I see the part I'm looking for until I have a conversation with the yard. Also, if it's an interior part, keep in mind a high percentage of these trucks have been sitting in that yard for a long time exposed to the elements with busted windows, doors missing, etc. so that kind of stuff is rarely in very good condition. Good luck!
