Anybody know where I can find 2 new manifold studs for the 300 I6 running a carburetor? The studs are 4.5 inches long, 3/8 inch diameter, with 24/inch threads at one end and 18/inch threads at the other end. The course end of the studs thread into the the exhaust manifold and the studs run up through the intake manifold to a fine threaded nut that hold the 2 manifolds together.
I found a replacement exhaust manifold through Dorman, but I can't find any replacement studs.

 

are these what your looking for?

That page is for a 1963 Ford 300, not a 300 I6 engine.

The 300 was basically a stripped out Galaxie, and 1963 was before the days of the 300 engine.

 

good catch....and color me embarrassed. I guess my PC just zoomed to the bolt picture and description....bypassing the application.

but from the description from the OP it would be something similar only maybe longer
