Broken exhaust manifold

Anyone have the part number for the exhaust manifold on a 350 cummins in a 2000 Alpine coach? Looks like its time to replace mine and check my turbo while I'm there.

If you have the engine serial number, Cummins care will provide the part number.

Tried that and no luck. It will work with any internal engine parts but not the exhaust.
I guess the exhaust depends on what type of application. If you search Amazon for 8.3 Cummins exahust you will see several factory Cummins exhaust manifolds. Irvine Cummins said to try and get a part # off the manifold.
