The TJ flares are a great way to get extra clearance on a CJ or YJ. Just get a set of flares, cut the rib off the back so they sit flat against your body and trace the outline of the flare opening on the body with a grease pencil or some chalk. Break out the sawzall and get crazy! There are some interference problems at the front of the rear wheewells, so the rear flares have to be positioned so you won't cut into the interior. Some inner front fender modifications are necessary, but they become obvious once you lay out the flares position on the fender. People sell the factory flares cheap after they sun fade from black to gray, just heat gun them until they turn black again and they look great. I got my last set for $60, with fasteners. Just do a search on Google for something like "TJ flares CJ" for some links to good info and pictures.
