Thank you for the order! To answer your question about the installation- The Load Guard is the only piece that goes up and over the section that is closest to the cab (AKA load-guard), so it really depends on how the cover is attached and where it is hinged. My guess is that you will probably have to take the bolts out (or loosen the clamps), slide the load guard in place and then put the bolts back in (or tighten the clamps). I would think that you could get away with just picking the cover up move it back a few inches (rest it on the truck rails). Snap the load guard in place then reinstall the hardware. Either way if you are having a problem feel free to give us a call, we would be more than happy to walk you through the the process. 1-800-992-1949
