What bolt size for starter?

[NastE50]

What size bolt is used on the starter for my 5.0?? My car wont crank over and everything up top looks correct so I jacked it up and sure enough, it is missing a bolt. I need to replace it and I don't have a bolt that fits. Thanks!

It is either a 5/16 or 3/8 in coarse thread bolt. About 1 1/2 in long.

Pull the bottom one and check it. The holes are threaded all the way through, I think. If you buy one, get a grade 8. These are near impossible to remove with a rounded head or other problem. Been there, done that.

Lack of the bolt should not cause the starter to not function, but might break the mounting ears off.
