Sunroof Dart (1973) Question???

In terms of 340 cars only, Mopar Muscle published that only 40 1973 340 Sunroof Dusters were produced. There were over 15k 340 Dusters produced that year. There were fewer Dart Sport 340's than Dusters, so I can only speculate that there would be less 1973 Dart Sport 340 Sunroof cars.

I have a 1973 Duster 340 Sunroof. I've had it since 2005. Since then, I have not been able to uncover much info on the subject. Another member (my340) has a thread on this topic as well. I think only a total of 26 or so Dart 340 and Duster 340 combined have responded. So my assumption based on the limited info out there is that 1973 A-bodies with the 340 and sunroof is very rare.
