Default 1989 Corvette Alternator Bolt
Hello - Anyone know the size of the top bolt for the alternator? The one that connects the Alternator to the motor. It is stamped 9.8 but I don't know how many MM it is.

Thanks in Advance

The top bolt that it pivots on through the bracket OR the support rod on the back side of the alternator?

Which # in this illustration?
