On the link above, number 5 is the part I am having the issue with. Well somehow my head got stripped where that pivot bolt is supposed to tighten into. I need to helicoil this location if it is at all possible but I need to know the specs on the bolt so I can order the correct coil and tap. Can anyone help me out with this?
