Review on 🔧 Enhance Your Truck's Durability with Dee Zee DZ16335 NXt Mounting Bracket by Mark Sharma

The instructions say 13mm on the tool kit but I used 9/16. When you start working with both wrenches you will need to tighten them firmly, but the inserts will eventually shrink. Of course, if you're lying on your back in your driveway, things get more difficult. I use Loctite for all screws. quality product.
