I need Carburetor Help for rebuild???

["Ralph Bade" <rbade@xxxxxxxxxxxxxxxxx>]

I am trying to identify the carb on the 401 in my
'79 Spirit. The carb appears to be a Motorcraft
4300 4-barrel, but all that is stamped or attached
to the carb itself is the Motorcraft stamp. On the
electric choke, it has the following information:
4FBS 3M218 RB 2KT1-4V

I need to identify the carb so I can get a rebuild
kit for it. It sits on an Offenhauser Intake that
is marked 360. So, I know the person that
installed this 401 may have been adding parts from
other cars. It also appears that the cover plate
and linkage for the carb for the "3rd & 4th"
barrel are missing, so I need to get those also.
Does anyone have an idea of what the carb might
be?

Thank you,
Ralph
