I'm after a prorack roof rack or similar for a 2019 Sportage to chuck my kayak on to, but the fitting kit K979 seems to be hard to find. On the forester, my last car, i'd actually put some parine ply on the rails and zip tied it which worked real well, but this thing has the flush rails. Any ideas on finding these fitting kits? They are hard to come by. The racks are the S17 and the S 26 apparently which I can get from one of the outdoor shops, but it's the fitting kit that isnt available until October. Thanks in advance.
