So yes, go buy 3 m8 2 inch hex head bolts, thick waters and lock nuts. Take out the taillight, bolt in the hinge bracket but keep it a little loose. Next, test fit the latch bracket. If it's too wide put it in a crack in the sidewalk and step on it. Do this till its the right size. Flip the nut n bolt on the latch catch so the Phillips Is on the ouside. Bolt the latch bracket in place. Flip the tie down point by the twilight tround. Attach the box, test fit the latch and adjust by moving the latch up or down and or adjusting the hinge bracket by putting the box parallel to the bed and move the end up or down till it latches. Tighten up the hinge plate. Tighten up the latch by putting a open ended wrench behind the bracket and turn using the Phillips. Load it up and go. Took me 30 minutes and I was done4 stars cuz the plastic is a little brittle.
