A while ago I posted a message regarding fixed ports. John, from Bohemia River, MD., wanted to know how I made out with a local supplier. I finally got the measurements and visited the shop. Within 20 minutes, I walked out with two new smoked lexan, cut to specs ports - cost $50.00 plus tax, as they quoted over the phone. For the information of all, the supplier is: Grim's Plastics; 6951-H; Allentown Blvd., Harrisburg, PA. Phone 1 800 745-8179. They said any orders will be shipped within 3 days. I don't think you can beat the price. Ask for Matt or Tom.
