66 Dart Trim needed

I have a 66 Dart Hardtop that I am trying to locate the trim piece that is just under the passenger rear window. It must be from a 170 or 270 model. The GT use a similar piece but are slightly larger. Mine has some pitting and Im looking for one the is in better shape. I am willing to trade mine plus some cash or buy one straight out. Here are a few pics of the front and back side of the trim.
Thanks RodDSCN0378.JPG DSCN0377.JPG DSCN0376.JPG
