Shawn, how much width are you limited by on your tailgate?
the TopLine 'shrinks' to 46 and a half inches wide.
i was impressed by the quality of the tailgate extender and the stainless steel mounting hardware.
i saw that the brackets actually lined up with our tailgate holes on our tailgate! trouble was i needed to drill out the supplied stainless bracket holes to about 25/64th... i burnt out several diamond tipped bits doing so and 4 14volt batteries... after all that. i get the sucker mounted into the factory holes with the factory tailgate screws, im really impressed with the quality and how well it works. i fold it up, go to close the tailgate and the *$&%()$ tailgate wont shut!!!
the brackets are sitting about an inch too LOW. so the bottom of the extender when its folded up hits the bed, pushing the tailgate up. so i have to remove everything tomorrow, take the brackets off, bring them to a drill press, and drill new holes into the bracket that will be about 3/4th of an inch 'lower' to move the the assembly up. that should raise it enough, to clear the bed floor while closing but low enough to not interfere with the tonneau cover.
when i get this addressed tomorrow i'll post up finished pictures. but if i do get this working, this system is really nice. If i had followed the directions, and just drilled new holes none of this would have happened. but i saw the spacing of the 1/4" holes on the brackets lined up with our tailgate holes, i jumped on it. shame on me :( i wasted a ton of time tonight....
