64-66 Barracuda Rear Defroster

Yup concur, my 64 Is completely optioned minus the rear defroster or the reverb speaker. You could only get one or the other. If you notice on the passenger side trim panel it has a long slit in it….. for the heater!! If they never did it you wouldn't have the speaker. If you have ever noticed some fold down rear panels also will go all the way across to the quarter panel, (non-defroster cars) defroster cars just cover the cargo area and use the trunk for a re-circ area……. or as told by Govier to me a few years ago…
