Not gonna lie, there are a lot of screws. With my friend and I each taking a side it took us about half an hour. Just so you know, there are two ten mils that you need an extension to get to. You get those by going through the space where I installed the light bar. Then there are two 7 mils that are hidden in the grill. We had to take out all the other screws first then grab the top of the bumper and pull it back just to see them.
Thanks! Did all of that when I had the bumper apart to mount the winch. No brackets required! The Rough Country light bar fit perfectly between the inner bumper brackets in the opening so all I had to do was drill two holes and mounted it directly to the bumper support brackets.
