Simple installation: Clean cart, put cart in neutral, lift the body of your cart up and out of the way, position diamond plate floor on or over rubber floor mat for best fit and look, you may need to push the gas or brake up a little in order to slide the floor in place, then install rivets or screws in all corners and in the middle sides of the plates
If you don't want to drill holes you can install using rtv caulk, apply rtv to the rubber floor mat, install diamond plates, let sit over night
