I did the hydro pedal assembally and now i have no idea of what size the assembally's studs size and pitch. I've tried 3/8-16 and a no go. It looks like its just a hair bigger than a 3/8 bolt. Is this metric? If so does anybody have any idea what size it is? I am going nuts trying to figure this out. Maybe it would be easier to take the studs out and put my own bolts in.
