Practice mounting the brackets to the glass to see how to get the best adjustment and tightest fit on the glass. Then mount the brackets on the glass, making sure that they are positioned to mate with the hinge on the stanchions, then trace around the brackets with a sharpie. Removed the brackets and etched or scuffed the glass inside the tracing with a dremel. This gives the cement something to stick to. I used contact cement to glue the rubber and brackets to the glass. During normal car maintenance, check the clamp screws for tightness.
