I have completely restored and updated a 1985 HM Coastal Barracuda. I had a windshield fabricated at a local plastic fabrication business. It is a single piece of gray 1/4' plexiglass. By using a protracter, I determined that the center bend angle was 150 degrees. Each side measures 38" and it is 12" high. E mail me privately at email@example.com and I will put you in touch with the company in Clearwater, FL that made it for me. They may still have the documentation. I cost around $300.
