I need to modify my cover and I have a 2001 Outback with a after market tower. I feel I can make 4 holes and modify with velcro or zippers to fit over the 4 mounts. My challenge is the draw string. My only solution is to cut in those 4 places and tie each time so that then I can draw it tight in the back. Without the obvious answer of take the tower down each time, has anyone any solution?

Thanks
