When removing the axle the last bolt decided to just spin in the flange. I cut it off with a saw but need replacement. I went to the auto store and got a bolt that is not an exact replacement but close. The splines are a bit larger but the guy said it may work in my favor being that I probably rounded out the hole when it spun. The other idea is just finding a grade 8 bolt and calling it a day. My fear is that the new stud is not going to fit in the hole and I'll be screwed trying to get it out.
