I'd recommend you order it from A&J Canvas in Vanceboro NC. (252) 244-1509 They do all the OEM canvas for GW. Did my 330 last year and it turned out great at a small fraction of the cost. Various choices of glass and canvas, better than than OEM is available. Although they have many of the patterns on file it's best to send them your old canvas and they will compare with their patterns to make sure GW didn't make minor changes. They provide snaps/lift the dot connectors/tools so you can match your current snap placement. There is a little work to be done on your end, but well worth it (unless money is no object). Shipping is fairly cheap and done in larger cardboard tubes. Good folks!
