    I have a new Tray and Jute with openings for Speakers. Does anyone know what the small square/rectangle openings were for originally? Maybe defroster vents?

    The small rectangular holes close to the seat back where actually for rear belt option. Never seen a factory one, only pics on the 'net. B bodies had then too.

    The large oval hole on the drivers side is for a rear speaker while the large oval hole on the passenger side is for the rear defroster fan.

      nope.
      rear air (defroster/defogger) "vent" on all mopars of this era is the long - rounded corner - slot located dead center of the cars rear shelf. That housed the black plastic duct & top trim. blower was mounted under side of the drivers side speak hole, with an accordian fabric tube connecting the two. applicable wiring to dash switch on left side.

      There was a 2nd style ( self contained type) used on some 1974-76 plymouth brougham 4 doors and the applicable dodge model as well as a few B-body 4dr and F-body cars (aspen / volare). that entire unit mounted within the confines of 1 speaker hole, no tube or duct and had a top cover that looked like a square speaker grid which almost never survive due to UV making them dust after a few decades.
