manifold to downpipe bolt ?
I've been searching but can't find the answer. How does the exhaust manifold attach to the downpipe. It is a 1985 300 carb'd. I took a quick glance and noticed the previous owner has a C-clamp holding part if it together. Is it just a stud attached to the manifold and a bolt in the downpipe side or can I use a new bolt and nut? Thanks.

If you are asking about how the exhaust attaches to the exhaust manifold then there should be 2 studs that screw into the exhaust manifold and the exhaust pipe flange goes onto the studs and has a nut on each stud to keep it secure.
If one is missing then the stud is broken off and would have to be removed and a new one installed or a different exhaust manifold would have to be put on.
If you mean something else please post a picture of it.

drop the exhaust pipe from the manifold and see if the stud is missing or broken. It can be replaced or if broken drilled, tapped and new stud installed.
