Is that aluminum he used, and how thick would it be ? You could easily use the original rubber from the top and bottom and sides. I did some metal work and am a jointer by trade, so it’s really just getting the aluminum. Cooldon't discount rolling your own it ya have time, local scrap yard can be your best friend, .190" scrap sheet, a little pattern making and I then cheated, dropped into auto cad, my buddy has a plasma cutter, Shazam, windshield frame.... dropped off at glass shop for glass/gasket...integrated into roof.
regret, didn't do manual windshield wiper...yet.
regret - overcomplicated vents
