Not actualy nuts, maby a little crazy........ hehe, that's why your here though, right?
I'm sure the original one is 15/16ths. That doesn't mean sombody hasn't replaced it at some point in the past with something else. I'm not sure what the thread size/pitch is, but I'll bet some other US brand crank bolts will fit but be other socket sizes. also, a bolt from the bin at an auto parts store might be the right size/pitch, but a different size head. Maby 1"?
