Your eyeball could be your most useful tool here. It took a few attempts at clamping the new section in place and standing back to look, not to mention several minutes of beard rubbing, before I settled on this location. The lower front section aligns with the existing fender edge, the swage line tapers off ever so slightly to the rear, and the compound curves match up way better than I could have imagined. It also visually lowers the truck, and-here's a bonus-I can still remove the wheel and tire. Just.
