I have a 1972 CS with 350 2bbl carb, auto trans with AC. I am wanting to put engine area back to original and need vacuum line positions. Pictures,or shetches would really help. Thanks alot. Previous owner has plugged alot of stuff on the caurburetor and on the engine components. Have no idea what goes where. THANKS as always

Do you have a '72 Chassis Service Manual? If not, you should get one. There is typically no single diagram in the manual with all of the vacuum connections. You'll need to look at each system to see how hoses are routed and connected. For emission control vacuum lines (EGR, PCV, charcoal canister), look in the emissions/tune-up section. For heater/AC controls, look in that section. For cruise control, that section. Power brake booster, that section. Etc.
