1976 Cadillac. Source for a vacuum fitting.

When I went to replace a vacuum line, the vacuum fitting toward the rear of the intake manifold just crumbled in my hand. Does anyone know who sells this fitting? I attached a picture.
Thanks,

I know the feeling.

What I did to solve the problem was to drill our the broken pieces to a depth of 1/8" two replacement tubes that I cut out of 3/16" and 1/4" Bundi Tubing, and and silver soldered them into place.   3/6" on top, and 1/4" in the side.

If you are just looking for something that functions you should be able to get a brass fitting from a hardware store and then a plastic vacuum T to hook the lines up. 

I'm trying to remember what hooks up there,  its the line to the parking brake and AC and what else?

Yes HD has those in the plumbing dept, same thing happened to me on a 75 Cadillac.  The brass will never fail.  Then use plastic tee, maybe elbow too.

One line goes to the level ride compressor, one to the AC unit.

The threaded outlet commonly available and a black T fitting would work just fine.

The hole inside is not the full dimension of the size of the fitting so it's designed with a smaller diameter as a restriction, but I can't see where full vacuum would change anything on these lines.

On my '76 DeVille, with a carb, the "top" line goes to the Thermactor(tm) air cleaner and the "back" line goes to the AC.  My car doesn't have level control.

The air cleaner makes sense.   I don't have that hooked up on mine so that is why I was thinking there was only one hose.

I thought the air ride compressor teed into the PCV vac line?   I have never had a car where the compressor worked so its been a while since I have seen one that was still hooked up.

The top one did go to the air cleaner.
