1970 307 vacuum diagram

I have a 1970 c10 with a 307 and a rochester 2 barrel on it. It's the stock setup. Does anyone have a vacuum diagram that can be posted? Even just an explanation of where each hose goes will work too. Thank you.

Somebody here has posted the chassis repair manuals. Check around. There are different diagrams depending on equipment. There were specific requirements for California vehicles.
