What a long strange trip it's been

It is a 2-door but no emblems or mounting scars from emblem, cloth interior.
could be a swinger special, vin number will start with (LL23G2) which is a cool car because swinger specials were low production numbers and make a good sleeper because the nature of a swinger special was to be a plain low buck car.

A regular swinger in 72 will have a vin starting with LH23G2.

Either way ….a good clean 72 dart is worth 2500. all day long
