Does anyone know what grade bolt & thread size honda uses? I'm going to helicoil and get a new bolt so I can put the mount back on.
i had to replace one of the bolts and went to the hardware store, they told me it was fine threads.It is a 12 mm x 35 mm bolt. The only question is whether it is fine or coarse threads. I suggest buying a bolt from Honda or from a salvage yard; then determine the thread pitch to determine the insert you need.
