What size bolt???

[five_o_stang]

Ok, so i'm trying to dissassemble a shortblock, and the dampener was already off so i don't have the bolt that held it on. Anyway, I need to turn the crank but I can't. A 9/16 bolt is WAY too small, and 5/8 is too big. So, what size bolt fits in the the crank snout?

I don't know the thread width or depth but the hex head is 15/16th for the harmonic balancer bolt...it has a washer that goes "before" it...

Stock bolt should be 5/8-18.

Shortblock is now dissassembled.
