Carb surge line to crankcase where is the bung?

[wesleypipes]

I'm so close to finishing my rebuild of my 1998 GTX Limited I'm looking for the bung on the crank case to connect the carburetor to, can anyone shed some light on where it is?

to be clear it is the #9 on this picture on the carb that should go to the lower crank case, I just cant find the connection on the crank case.
