Would this be a dealer installed option?

Just resurrecting an old thread here with new information. I finally sandblasted the old hitch I got with plans of painting it and installing it this winter. As stated above it is made by Draw-tite. It is stamped 1967-72-73 Valiant, Demon, Duster. The pictures aren't great but it's the best my phone could come up with.
