Kent - The part that Tom is searching for isn't the remote to lock actuating "link" that you have pictured. It's actually the "remote" that the door handle attaches to shown in the attached pictures of the door inner support panels that I found offered on ebay earlier tonight.
I found several sellers offering those panels with the "remote" still installed and will post the links in Tom's "Truck Parts Wanted" ad shortly.
