Vacuum source for choke pull-off

Hi:

What is a good vacuum source for the choke pull-off on a 72 350 rocket with the stock Rochester 2 barrel carb? Would this be a vacuum port on the carb or manifold?

Thanks,
Will

I am pretty sure it would be manifold vacuum.

Isn't there a little port right by the pull-off diaphragm?
It's been a while since I played with a 2-Jet.
