Chrysler calls it a "Panel-B" the part number is on the underside and it is dependent on the color. I bought one brand new in 2019 Part # YA72XDVAA for $34.56. I doubt there any new pieces available at this time. It is very difficult to remove them without braking a tab, so expect anything you buy will not be completely whole. There are clips ( I think two) which are slipped over the metal frame at the bottom edge of the quarter window and clip onto the plastic trim piece. These are particularly difficult to remove. When I re-installed the new trim I bent those clips so they would be easier to remove (there are barbs which dig into the plastic and the metal) if that should be necessary in the future. Hopefully that would help removal without damaging the trim piece.
