Bolt Size needed

[wrc3]

Does anyone know the length, thread and width for the bolt that connects the Alternator adjustment bracket to the engine on a L-48 350 1976? Looked down today and discovered it was missing. It is one of the bolts that appears to connect through the water pump and into the block.

Thanks I appreciate it. Now I am just wondering if the guy who owned it before me forgot to put it in, or snapped it off in the block...ugh.

If the bolt head is gone and no coolant is leaking, it's probably broken off - those bolts go through into the water jacket. :eyerole

Believe it or not it was just missing. I don't know how you would lose one of those, but it looks like the original water pump and I know it is the original block, so go figure.
