Brake Booster 1963 Colony Park

[ChiefDanGeorge]

I've been tracking down a brake leak and found out the master cylinder was leaking into the brake booster. I managed to snap the plastic nipple that the vacuum line hooks to. Does anyone know if I can get a replacement for it. In the shop manual it's called a Vacuum Manifold.
Also, how the heck do I removed it from the brake booster? I think it's just a rubber grommet that holds it from the inside. I'm trying no to break anything else so I don't want to start pulling and mess up the booster. Looks like the brake fluid was only in the bellows, which I assume would mean the bellows are still fine.

The fitting is held into the rubber grommet with nibs on the fitting.  It will come out pretty easily with a screwdriver between the flanges.  There are replacements available.  Your booster should be okay if you clean out the brake fluid.  Soapy water should do the trick.  No solvents.

So just take a screw driver and pry up from the outside, making sure to catch the grommet on the inside?

Put a screwdriver blade between the flange of the plastic manifold and the lip of the rubber seal and pop the manifold up.  It is a lot easier than you are thinking.  It comes right out.

Yep, it just popped out.

Now, any idea of where to source one?

It's very common.  Here's the most common:  https://www.rockauto.com/en/parts/dorman,80190,power+brake+booster+check+valve,1876

The ones with the second nipple are also around.  Just do a search for it.

If you are replacing the booster hose, make sure to use hose made for this.  If you use heater hose or similar, it's liable to collapse.

As an FYI, that is not the right part, the brake booster I have has a much larger port. I'd ordered the Dorman 80189 piece since it came with 2 grommets, but those don't solve the size issue either.

The part number I need is: C4AZ-2365-A, found it here: https://www.macsautoparts.com/1961-1971-ford-thunderbird-power-brake-booster-check-valve-66-36174-1.html however I'm trying to see if there is a solution that will work with a more readily available valve.

Don't listen to me, the 80189 will work, you have to stack the 2 grommets. Not the best solution, but it will work.
