I have to cut the front body mount as well. I am looking at the replacing my 285 Hankooks with the same tires except make them 315s. I have been pleased with my Kooks except when in clay where the KM2s might be a better tire. I justified buying a hobart and new grinder two years ago to do this body mount chop. I also bought a "how not to procrastinate book" but have not found time to do either.
