Great product, can't wait to smash them into something.
Installation tip: mount the sliders to the body via adjustable slider clamps and then punch all side holes to be drilled (drilling the middle three with it attached wont happen because the bar prevents the drill from accessing these). Remove the slider and drill all 5 side holes. Slather the inside of the slider with copious amounts of RTV sealant on the areas which touch the body. Reinstall the slider with clamps and install the 5 side screws. To install the rear screw, a hole must be drilled in the bottom of the body which is large enough to fit a finger with a washer/nut and a crescent wrench to fit (tip: a dab of silicone on your finger keeps the washer/nut stuck to them making it easy to thread the screw on). I used a hole saw bit used for drilling holes in doors for a dead bolt. Now drill the four bottom holes and install the screws. Let the exposed silicone dry and peel it off and finish with a nice bead of silicone on the exposed edges to keep the water out.
