inherited dodge dart swinger

Looks like you might have a "spring special" there. It was an option that usually came with A/C, vinyl roof, rim blow steering wheel, those rocker moldings that have a slight bend towards the rear as well as blacked out below the molding along with some hood lip moldings IIRC. If you have the fender tag and I'm correct it will be on it (A 42 ??) or something similar. Just an observation from your picture. More pictures would be awesome. Nice car and good luck with it.
