II did mine this past season and here is the info on what you need for a decent replacement - I had looked online and the only thing I could find were custom curtains that were very expensive
My original cabin interior curtain smelled of mildew and literally fell apart this year, so i decided it was had time to either replace or eliminate them. The boss made the decision we need replace. I removed the old one and saw that curtain slide were custom with sew in slides. A few on line...
