68 am fm thumbwheel. ultra rare. once in a lifetime find

ok, so it is now sold. Yes, my 70 340 duster came std with a rallye dash and a thumb wheel radio which is missing. Standard dusters may have had a round knob radio, but if I understand correctly, all 340 cars should have had the rallye dash. I am trying to figure out which radios and years will fit. Glad someone got this radio and appreciates it.
