I have on my 2003 F-150 flare-side the soft tonneau cover, the one that has the tounge-in-groove to strap it down on three sides. My problem is that the cover is coming away from the box right behind the cab, where it is supposed to be fastened down all the time. My dealer installed it over 4 years ago.
Does anybody know how that part of the cover was fastened to the box? I just can't see anything obvious. What do I need to fasten it back onto the box?
