72 400ci Exhaust manifold stud pattern

[dasol7172]

Hi all,

Trying to replace this cracked manifold. I have it back on but that last hole in the manifold is real deep and small.. There is a stud down there.. how do i get a nut on that? (when i pulled it there was not a nut on that stud.. and i thought it odd at the time)

Or... Have I been screwed again by the previous owner, that there should not be a stud there but a bolt?

the current setup is:

[Bolt --- Nut]-----[Nut --- Nut]------[Bolt --- Nut]

Drivers side stock manifold.

Thanks for any help.. this car is trying my patience.

For that last hole you need a barrel nut like shown on this Y1 link. All the holes take studs.

Ah ok great. I was reading also there are shoulder bolts that are used in some mopars.. I wasn't sure what I should be looking at.
