Here is a video showing how to lock down your truck body to the bed of your truck. No drilling, screw, bolts or anything else is required. All you need is a 9/16 socket wrench with extension.
When locking the body down to the bed, make sure you feel the lockdown with your hand and make sure that it is coming up under the rail and NOT into the side of the bed.
Make sure you tighten lock-down system tight but not too tight where it puts stress on the bed rails.
