EGR tube/exhaust manifold boss question

[TK]

Does anyone know if the EGR tube boss that's welded to the exhaust manifolds
is a standard part that can be obtained like the O2 boss?. I have a 3800 V6
exhaust manifold and I need to add the boss for the EGR tube. It appears to
be a 1/2" pipe thread for a compression fitting.

EGR's are EFI related, right?
