Vacuum Diagram for Air Conditioning 70 Chevy Pickup

Hello and Good day guys.. Does anyone have a diagram of the vacuum hoses for all of the air conditioning hook up. To include from the AC controller, the two vents, one in the cowl, the one in the right hand passenger side panel, the vaccuum canister? And I believe their may be one more unit of some type that has something to do with the system. The guys at the shop are trying to get this working for me, but are having a lot of trouble.. If you have specific knowledge and could help me, i would appreciatte it so much. I will gladly buy you lunch and pay for phone calls so I can get this figured out. Either case, a diagram or expertise would be greatly appreciated.. thank you very much. Appparently they have exchausted all sources trying to get the proper diagram. All they have found so far is what goes back to 74. thanks again..

I know,, I just don';t have one at the moment, and the shop thought they did have it so I didn't go out and buy one. I know most of the truck like the back of my hand so have never needed one. But the vaccuum diagram I don't know.. .. So I am looking for some quick help, so they can get my truck done without costing me a fortune.. I can't get the book by tomorrow morning.. Mabye you or some one of the brotherhood of chevy truck could fax me a copy of the page with the vaccuum diagram?? that would be really appreciated.. Please.. or scan and send via email??

Hey Fast71,, Your right, I believe we are here to help out eachother. And I thank you very much for that you just sent. That is exactly what I needed. The mechanic was trying to tell me that there is a couple of vacuum devices under the dash up above the heater control assembly on the fire wall. But I don't recall anything of the sort. I thank you sir for that diagram. Very much appreciated. And if I can ever return the favor, you know I will.. thanks again.. Barry
