Rarest A-Body Option?

I think BIGMAKDAK hit it with the Optional tape recorder.

Have you ever seen one of these? Probably not. I was also told by one of the former engineers from Mopar (He was also one of the Original Ramchargers) that there was a CB radio option but he could not confirm for A bodies.
I have seen plenty of sholder belts, rear defrost sport mirrors etc. but never ever a CB or Recorder in an A body that was factory in person but have seen the option for Recorder listed on line.
Great looking cars everybody thanks for all the post and all the help and info that all of you add to this site.
