hey guys. working on my 69 Camaro that I bought in boxes last year. The front doors are missing the 2 pieces that protect the glass as it slides up and down. They are steel plates , one on the front and one on the rear of each door. Held on by two small screws on the top. the door fuzzy actually covers the screws and they are covered with a material that looks like canvas. Anybody know what they are called and where they can be purchaced? thanks! Steve
