What size plug is needed for mac headers?

As Toby said M22 fits MAC headers. I found the oil drain plug for the Dodge Cummings Diesel at AutoZone. AutoZone number 090-151.1 It fits really well, has a washer and it has a drive hole in the head that a 3/8's rachet fits for installation. It's also nice and shiny to match the headers.
