A surround molding module incorporates an invisible division bar assembly. The invisible division bar assembly includes a support or glass encapsulation that does not extend outwardly beyond the plane of the exterior surface of fixed and movable windows of the vehicle. It provides a butt joint between these window edges. The support also carries a guide member that guides a guide leg extending outwardly from the movable window. An effective window guide tracking system is provided that has reduced wind noise and a flush window appearance with no off-set.
