So, I am in the process of doing a boatload of PM to my new (to me) '97. The brake system needs to be flushed and I am the man to do it. I am walking around the rig loosening all of the lug nuts before I jack up the rear of the vehicle. I get all of the hex nuts loose and move on to the security lugs. First one, loosened. Second one, POP! One edge of the nut broke off. To make matters worse, the pattern in the key was marred so that it doesn't work on any of the other security nuts.. Any Ideas about the best way to attack this at home? My tool selection is somewhat limited(no compressor or air tools...). Thanks.
