Does anyone know the size of this bolt, length, pitch?

For a 2003 2500 5.7l, lower idler pulley.

Had been having a weird noise every once in a while and finally got around to replacing the pulleys today only to find the lower idler pulley impaled into the water pump housing. Enough to say the bolt was snapped off and I cannot find post or size or manual that has the correct information for this along with now having to do the water pump unit too due to the mount snapping.

The parts books and manuals all vary on what is correct so I am looking for help on this one.


Thank you a ton in advance for the help

looks like the bolts in both upper answer lower are the same size.
