OK before I order some Rally Sport mudflaps I wanted to get an idea of the process. It looked not too difficult but maybe easier if you get the wheels off. Other than a couple the factory fasteners not getting reused does the car need any modifying, cutting, etc etc? I want a pretty simple bolt on thing and the video makes it appear so. But just wanting to get an idea. The rear ones look a bit tougher as there's fasteners near the exhaust.
