Its glued to just the flare. When replacing, try to remove as much of the old double-sided tape strip as possible and remove the residue with gumout or mineral spirits. Glue it back on by applying a thin layer of 3m black weatherstrip adhesive to the edge of the flare. Wipe up any that oozes out immediately with mineral spirits. Don't use the clear emblem adhesive that comes in a similar tube because it can damage fresh paint. Never broken any studs removing the flares but I figure they could be drilled out very carefully and replaced by probably applying some epoxy and inserting a new stud.
