bolt size for alt bracket?

[Evans Ward]

For the Y shaped bracket that bolts in 2 places to the alternator and once lower at exhaust stud, what is the correct size of the bolt through the bracket at the lower position of the alternator near the valve cover corner? I'm missing that one and need to know what size to pick up one at the hardware store. Thanks if you can help!

The lower aft bolt on a factory alternator is a 10mm X 1.5 thread pitch. THe factory bolt is about .75" long and has a 13mm hex size. Typical 10mm bolts have a 15mm hex. (Japanese versions have a 14mm hex, along with many hardware store versions.)

Many thanks there for that helpful info. I'm sure I can source one from the local hardware store.
