Help! What car is closer in shape to a 1973-76 Dart Sport The 1972 Duster or 1972 Demon?

I have kinda a dilemma here.
I ordered a custom car cover for my 1973 Dart Sport 340 at a web site the cover and is not right. Come to find out they do not make one for 1973 up Dusters or Dart Sports and should not be listed.
Looks like the closest is going to be 1972 Duster or 1972 Demon. The company was supposed to refund my $ but so far has not will only send replacement.
So have to choose from what ever one is closer. I removed the bumperettes long ago.
So what front end shape matches better or is longer from the doors up the 1972 Duster or Demon?
