So much fun, I can't wait to do the rest of the fun stuff on the K5. Used a sawzall, hack saw, and big old angle grinder. need a new disc or I would be done. My back hurt when I was done cause I was bent over the axle for about 30 minutes straight. Shaved to about the "washer" part of the bolt and plan on going just a tiny bit more and rouding the bottom of the housing as much as I can. I really want to start crawling and trail riding so ground clearance will be a plus.
