Crankshaft Bolt Holes stripped

[TunedUp]

Hello Everyone,
So my issue is pretty depressing, because while I was torquing down my flywheel bolts one of the bolts stripped itself and the crankshaft. I know how to tap it for new threads and helicoil it, but I have no idea what the thread pitch/ bolt size is to tap it for. Anyone mind assisting me with either pointing me to a thread with the answer or if you know it off your head it would be greatly appreciated. I have searched in every way possible on here, and in Google.
