Anyone know what type of fitting is used on the back of the intake manifold that goes to the vacuum pump/booster? I picked up a manifold for a swap and I need to plug it but not alter the intake. See photo below, not my intake but this is the are I'm talking about.

It's a compression fitting. You may be able to find a brass plug that fits at the hardware store or something, otherwise I'd just push the plug in and cap that whole boss somehow if you aren't using it.
Unless they come with them when you buy one from the dealer I've never seen that piece before. When you pull one off a car all you get is what you have, so sorry if I didn't understand your question before.
That black piece is just a plug to seal the fitting. You can pick something like that up to seal the fitting, but I don't know the exact size. Poke around through this google search and you should be able to find something that will work:
Rear Intake Manifold Fitting?
