Exhaust Manifold Stud Question

[CJPilot]

Anybody know what size (thread and length) the stud and bolt that hold the exhaust pipe to the exhaust manifold are? �Mine are rusted to nothing /broken. �Manifold itself is rough. �I acquired a replacement manifold but it�s been tapped oversize. I�m thinking that maybe a Keensert would work well in this application.

Thanks in advance �

One of my spare manifolds has a 5/16"x2" in it. I think it's original.

Carl thank you for the information. �It figures, my manifold has been tapped out to 1/2-13. So a Keensert �would end up 3/8-18 or 3/8-24

The Parts List shows...
one Bolt, hex hd, 3/8" - 24 x 1-1/4"
one Stud, 3/8" - 24 x 1-3/8"
two Nut, hex, 3/8" - 24

I think the stud may have coarse threads on the manifold side.

Thanks Bob. �If the stud is in fact 3/8-18 at the manifold then I�ll try a Keensert and see what happens. �I have not previously used one

I'll be replacing the stud in my spare manifold. When I went out and slapped a caliper on it it read real close to 5/16" and I posted that. But the truth is it's worn out and a 3/8" nut just slides right on it. Now I'm wondering how they made that work.

Sorry about the miss info.
