Abstract: A liftplate for use in a window mounting assembly includes a first plate member, a second plate member and a third plate member. The first plate member has two spaced apart apertures and is secured to a window regulator. The apertures in the first plate member each have a sleeve molded therein. Each sleeve is attached to the first plate member through a frangible connection which is broken upon insertion of a fastener in an associated one of the apertures of the first plate member. The second plate member has an aperture which receives one of the fasteners. The third plate member has an aperture which receives the other of the fasteners. The second and third plate members are disposed opposite the first plate member and are joined to the first plate member to define a channel for receiving a sheet of window glass.
