65 Barracuda daily driver

Finally some more progress on the A/C install. Took forever, but I mounted the condenser today. I had to make some spacers so it wouldn't touch the radiator. Now I just need to mount the compressor, which is really just 4 bolts at this point, connect all the hoses and hook up the vacuum lines. For that I need a vacuum port for the intake manifold. Does anyone know what thread size would fit on a super six intake? Are they all the same? Where can I get one?

See that shiny bolt in the center? The original one was too long and poking into the fins, so I had to use a new shorter one. It's those little things that are soo time consuming.
