Bad Luck! rear window trim 72 dart

Dam!!!!! I was driving the dart today and the bottom of the window trim blew off. S.O.B! I knew it was loose but didnt take it off. I was perfect....untill the cars behind me nailed it.

Any way. I looking for the bottom piece of window trim for a 72 dart. Let me know, i would like it in clean condition but am open to what you have.
