A trim panel assembly for a vehicle is provided having a pillar and a trim panel adapted to attach to at least a portion of the pillar. The trim panel having an upper edge and a lower edge. At least one ledge extending generally orthogonally away from the lower edge of the trim panel. The assembly further includes a headliner, the upper edge of the trim panel abutting the headliner to compress the headliner when the trim panel is in an installed position. The trim panel is adapted to closely abut a headliner wherein the ledge provides the installer to apply a greater force to the trim panel during installation to provide for a greater headliner crush. In order to finish installing the trim panel, the installer must push upwards on the ledges thereby creating greater interference with the headliner to properly secure the trim panel.
