where the hell do I find these

I heard both chevy and ford used these drop down tie rod ends. the only 2 things I know are that they came on some trucks, and I need em. parts stores haven't been much help. I thought maybe some of you guys might have some ideas. These are the only things keeping me from wheeling.
HELP
thanks everyone, Chadc
