Opened up my gearbox after hardcore road racing on 800ft/lb tq engine.

I thought you wanted M7 bolts?

ah yeah, I think fine pitch is stronger. I can't find above grade 8.8 was going to just do real mccoy's method.

Isn't stainless like grade 10?

I would just peen in a solid pin or use that fatter pin trick above. Finding a bolt with the proper grip length is damn near impossible, and I would never install an all threaded bolt in a shear application. Threads can not support shear loads and will smash, allowing the fork to move, and will eventually shear apart.

Thanks for the input guys, I'm going to try the dual roll pin approach as it seems the most fool proof.
