yes, one on each bank, one is used for the servo vacuum connection the other has a blanking screw in it (allen head). Not sure on size but it looks about 12mm hole. Front two pots facing slightly inwards below the throttle plates.
Damn! I was hoping for one on each throttle body! I've found quite a nice unit for balancing the flows but it needs to screww into the body rather than fitting over the opening!
Ah, we are at cross purposes here. I thought you meant a big vac take off. There are 8 small (m4??) blanking screws on the outside of the bodies but not sure if they are above or below the plates. I can check later if nobody else can answer the question sooner.
