These fenders are a breezy to install, I've never don'tmy own work on cars so I am a newbie, so if I can do it, so can you. Took me about 2 hours (including removing factory fenders). They look great, had solid screws, everything lined up perfectly so didn't need to drill myself and even the self tapping screws were easy for the rear fenders. Instructions says drilling is required but thats not actually true, the self tapping screws to the drilling so you don't need to drill holes first. I love the look of these on my jeep. They did not bend against the rocks I needed them to protect the jeep on. Definitely recommend, specially for the price!
