If you want to remove them be sure to look around the edge of the moulding to make sure that they have not been painted around,If they have you will not want to remove them unless you intend to do some paint work.When we remove mldgs at the shop I pull them off some time using a narrow putty knife but am careful not to scratch the paint.Another thing you may want to consider is depending on the color of your truck where the mldg was may be darker especially the Gen 1s without clearcoat.Several tool company make mldg removal tools.
