Thread Size For EGR Port on Exhaust Manifold

[mlochala]

On a Mountaineer with the 5.0 v8, what is the thread size on the port where the EGR tube connects? I had to do some repair work to my manifold this week and discovered these threads are also slightly damaged. What die do I need to get to repair these threads?

Go to your local auto parts store and take a look at the oil drain plugs, on my 5.0 swap I had to plug the EGR on the manifold and the largest oil drain plug they had worked perfectly. It's the one that use the box end of a 3/8 ratchet to tighten down. Either 18 or 22 mm i think the package said.
