Abstract: Rear view mirror mounting brackets are adhesively bonded to a windshield using a relatively small, portable rework fixture that can be temporarily secured to an automotive windshield by means of suction cups. The framework of the fixture supports a pair of movable guide rods connected to a metal block equipped with a heating element and having a surface that holds the adhesive coated mounting bracket. The guide rods are equipped with compressible springs that maintain the block and associated mounting bracket in close contact with the windshield during curing of the layer of heat-curable bonding adhesive present on the surface of the bracket that is in contact with the windshield.
