rear window defogger vents and blower for '67 Barracuda

I have never seen a set of rear window defroster vents, nor the blower, offered. I don't know they even made vents and blower for a '67 barracuda. I do see that there are holes in the deck plate for these, and I have seen a blower for a '68 charger. Can anyone shed some light on this? Thanks, and stay safe..
Fastback or notchback?
