Big eyebolts in the front and rear corners. Used big Nylock nuts and washers on them. I put them in the hole already in the sides of the square holes that are already there. You can hold the nuts from the top and use a screwdriver to tighten the eyebolts. Puts the tiedowns kinda high on the bedside, but it works for my dirtbikes without issues, and no holes to drill in the bed.
