Hi Steve and Sherri
As far as your zipper, one place I can think of is a tent and awning repair store. We have one here in Phoenix and when we had trouble with our awning I took it there. They were very good and I had my choices of zipper. If the pannel comes off easy, maybe take it in and see what it would cost to have them do in?
