I searched for a way to install a glare shield where none existed. This worked great. They are reasonably priced for the labor that goes into making one. They are a quality unit, not cheaply made. It is light yet strong. Contrary to the internet research I did these are not shiny and reflective in the windshield. They are a mat black and are perfect for a glare shield. They are very closely fitted to your exact aircraft but may take some minor cutting/sanding to fit properly. One issue I had on my 210 is there is only about 1/16 clearance between my windshield and the panel but the glare shield is about 3/32 thick. They are fiberglass and sand easily. Be careful not to overdo it. Go slow and measure carefully before cutting.
