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

In my 68 I have the dash switch, and the deck vent trim. But in 1988 I was more interested in 2 speakers, plus living in Fl, I wasn’t worried about a rear defrost, so, being young & dumb, I tossed the blower motor & 6x9 hole adapter
