th400 intake manifold vacuum

[obijuan]

ive got a question about where some stuff is supposed to go.

my brake booster goes to this "T" with only one side on the back of the intake manifold. and ive got to attach the vacuum modulator to the th400.
where can i get a two prong "T" that goes into the hole behind the carb, the parts house here didnt find one in the help or on the computer. not sure where to find one and junkyards here are few and far between.

so i need a tee with the big prong and a little one that screws intot he back of the intake.

Is there a fitting at the front of the carb? Or are you running a Quadrajet? Or PCV system? I don't know what would have come with one from the factory. If you found one, it might be a big tree...with 3 or 4 ports on it. Or it may be a thermal switch. You could try hitting the hardware store, check in the plumbing section. If you can't find the fitting, I'm sure you could piece one together.

There isnt a vacuum port on the carb you could attach it to? When I first got my pickup my brake booster attached to the quadrajet carb. On the intake was a 3 port fitting in the intake where the cruise control,heater controls and the transmission connected to.
