I you must keep the bed liner, notch it, or better yet, cut the whole lip off. I would use a dremel tool or a jig saw with a fine blade. But, as others have said, the drop in bed liners are a sure way to loose your bed to rust. The vibration causes the paint to come off, then trapped water starts the rust. You should at least pull that liner to see what is underneath.
