I am installing a 3.0 v6 in my 3.0CL. But the throttle body I have seems to be missing a vacuum port(See picture). I have a hose that goes to it, for the FIA(Fuel Air Injection). My question is this, has anyone seen one like mine, with a hole that looks something should be there, but is actually only drilled partially and doesnt go into the air inlet chamber. Should I drill and tap a new vacuum port? Thanks! The small hole I am referring to is right under the screw, this is the top of the throttle body.

 

So, I decided to go with another junk yard throttle body. This time with the correct port. I found that this vacuum line does go all the way through. But it is a very small hole. Anyway, problem solved.
