Rarest A-Body Option?

I've got a '71 duster 340 that came with a dictaphone on the floor non console 4 speed.... console 4 speeds, radio and heater delete, cruise control, sunroofs are all rare on any a body. Things that are rare in some areas are not in others, like most Canadian cars had engine block heaters and a lot had rear window defoggers but most southern U.S. cars did not. I would say a very loaded up 340 or 360 car is unusual, I also have a '74 360 dart sport that is white with white stripes and that's rare as well. Just to name a few....
