Need bolt size

[BADINBLACK6]

I lost the mounting bolt that goes to the back bottom of the altenator, anyone know what size it is?
Thanks Chris

To me it looks like the same size as the top bolt, where the torque strap goes.

it's a 7/16" bolt with a 16 pitch, 3/4" long and mine has a 13mm head on it.

If this is a stock alt, what John said is correct, 10mm thread and should have a 13mm hex.

Dan is also correct as the "top" bolt and nut is the same with 10mm threads.
