Exterior molding/trim question

Your trim should pop off the little square plastic thingys.I just replace all the square plastic trim holder thingys on my 66 Dart.I ordered them from RT Speacialties.After removing the trim you can take them off by tapping the peg in the center out.Here,s a pic of the square plastic trim holder thingys LOL.Good luck!
