The first thing you need to do when doing a windshield replacement on an older corvette convertible is remove the targa top. This is done with loosening the front two torque bolts, not removing them. They are behind the sun visors. The next step would be to locate the three bolts on each side of the rear, but only removing the center bolt entirely on each side. Push on the front of the top, then lift to release from the rear.
