The pic below is all the mounting hardware. Just little plastic U shaped things with 3 screws each for the cover bar and the other two mounting holding the end of the top when you open it up. I really just went in there and held it where it seemed to work best. Marked the locations then I held the bracket there and used a driver to put in the screws. I used a drill driver, but a regular screw driver would have worked just fine. I didn't predrill, but you certainly could and might want to.
And, yes, most of the time on the install was just figuring out where I wanted to put it as I was apprehensive about putting holes in this thing. If I allow the seat to recline all the way and put the cover behind that, it will leave a good size gap between the seat and the cover when the seat isn't reclined. So I reclined the seat back a bit farther than we would normally use and put the top there. So enough room to recline it back some, but if you want to go farther back, we'd have to remove the cover. I doubt that will ever happen around here. Once I figured that out it was about a minute for each side to get it installed. And now I do keep my emergency stuff back there.
