The plate will come with hardware (stainless steel replacement screws) and install instructions. Basically, utilizes the bottom oem cladding screw locations. Mostly this method will suffice to secure the plate to the cladding. However, because cladding differs from one to the next, you can replace the top cosmetic screws with self taps. I just replaced the top two outter corner ones as the corners were lifted and this gives it a cleaner flushed look. Others have replaced all of the cosmetic screws all together. Hope this helps.
