+1 The cut up bedliner will haunt you later.I would not use this bed liner that came with the truck. Once cut water and debris will get under the bed liner, this will cause rust. My bed liner is in the attic for sale. I had a sprayed in bed liner done after the railes were installed. I then removed them had the Line-X installed then reinstalled my railes. Tjis is just my $0.02.
