67-69 Barracuda Notch Rear Seat

Hi everyone. Found out today my rear seat is actually from a '72 Duster (after blasting and powdercoating the frame, of course). I need the rear seat frame that will fit my '69 Barracuda Notchback. Condition doesn't matter since they'll be blasted, powdercoated, and reupholstered. I have a potential local source for a bottom frame, so if you only have the top that could work too.
