Tom, without knowing all the geometry involved I can't build a mold to form an adapter. I have emailed my plastics friends who make larger things (like boat windshields) about the feasability of making the lens. Problem with that will be we would need to come up with a true sample or an official U-Haul
dimensioned drawing with the various radii callouts. How big is the lens? (L&W) and if you were to put it on a tabletop with the radius that goes around the corner on top, how high is that?
