front axle bolt is the EXACT same thread, use that and save yourself time and money. I destroyed my original axle bolt getting it out when I was stripping my X. I got a spare to replace it, so now i use the destroyed one as a flywheel puller O and I destroyed the head, not threads trying to unscrew it, so I have to put vice grips on the end to use it as a flywheel puller. Good luck!
