||My new to me 26 came without the sliding screens. I contacted Dimond Sea Glaze and they said that they only provided them with new windows. I then worked with Three Rivers, as they might be able to leverage C-Dory, but they came back with the same previous answer. Searching on line proved futile, so I ordered parts from an RV supply company. The forward top and bottom corners were heated to bend then to the correct shape. The frame is aluminum, but all ends are plastic.
