Vacuum source
Trying to get my a/c working, found out it doesn't have a vacuum source to the controls inside. Had to take the dash a part to find out where the hose line (black) to the controls came out under the hood. Found the right hose running from the controls out through the firewall, now I need to find out where it gets its vacuum source from, any help would be appreciated.
It's a 73 350.
Thank you

It normally feeds off of the vacuum fitting on the manifold just to the rear of the carb, but you can use any direct manifold vacuum source.
