4.0 exhaust manifold stud

Does anyone know what the thread size of the exhaust manifold studs on a 4.0 is? I have one that backed out and fell off. I went to the bone yard and he gave me a bolt that is used on the intake manifold but it doesn’t work. I thought if I got the right thread size I could use a bolt. It would make things a lot easier, then trying to locking in a stud and using a nut.

Thanks
John
