It is square, 6-in by 6-in. I attached 4 photos showing the top, bottom, and two measurements of the "T" slot. It came with my Charger (did not mate with the jack) and obviously is not factory equipment. I've checked out Nick's Garage but no matches. Thanks in advance.

C body I believe. Slightly larger than b body jack
Hey there,
Did you ever figure out what it came from. I have one very similar, except the hole has a circle.
