Identify factory sway bar piece?

OK, guys I finally got back to this. Either I've seriously lost "what I thought I had" or what I thought I had is not "what I thought I had," LOL

This thing must be for a Chyrsler Impervious, or maybe a Lincoln Continuous, LOL What you see is this bar lying on an 73/4 A body /6 spool mount K frame. You can see "it's a little wide."

Measures 44" outside. Anybody know how wide an A sway ought'a be?
