Have you ever seen any Dart, Valiant, Demon or Duster with a rear window defroster?

My 70 duster was originally a gold duster package. It came with some options, sport front seat(head rest, arm rest), rear window defroster, rear speaker cutouts. Soon after I talked my mom into a 73 gold duster, none of the above, but map light, trunk light, glove box light. So I preceeded to find all the harnesses I needed to add all the options she had to my car. My car is now a 340 duster with all the gold duster options.
