Here is the Jeep prior to installation
I removed the fender extension and two screws from each fender flare by where the rocker goes and put a fresh coat of wax where the rocker was to be mounted.
I used Tough Stuff rocker gasket material to prevent rust and to protect the paint
I then used a jack to hold up the guard and mark the holes
After marking the hole locations I dropped the rocker and I drilled the holes for the sides and floor with a 3/16 inch bit then a 3/8 inch bit which was the final size.
I used a product called auto goop that I picked up at my local automotive parts place as a sealer. It is similar to silicon caulking but also acts as glue. I used it on the bolts and the washers to waterproof the installation. I have used this product many times and it works quite well.
Big Daddy included all the hardware but there was one issue. They sent 2 3/8” x1.5” grade 8 bolts with washers and locknuts and 2 3/8” x 2” grade 8 bolts washers and locknuts to go through the floor. The 1.5” long bolts were not long enough and the 2” ones where good, I ran up to the hardware store and picked up two 2” long grade 8 bolts and finished the install.
