Frameless soft top 2001 Wrangler won't fit, cannot get back window to zip to side windows, 2 to 3 inch gap. Side windows are zipped to top and are very tight. Got it to fit last spring after leaving it in the sun for hours. It was still a struggle and I thought the zippers would fail. After leaving it on for 2 - 3 weeks I took windows off for summer. Advice?
