Stock Crank..
But I heard about crank ID.?
Bearings size may vary for each crank?

Thanks any help.

 

crankshaft O.D...outer diameter

I would think you would be ok with a standard bearing, if nothing is touched. If you have a mic you can measure the crank and a dial bore gauge to measure the saddle. But, in my opinion, if your this far off you should take it to someone. Or buy plasti guage. It seems beginner friendly
