* Repair Manual: A Haynes or Chilton repair manual for your specific year and model Monte Carlo will be your best bet. These manuals usually include detailed vacuum diagrams. You can find them at most auto parts stores (like AutoZone, Advance Auto Parts, O'Reilly Auto Parts) or online retailers like Amazon.
* Online Forums: Search online car forums dedicated to classic Chevrolets or Monte Carlos. Sites like Monte Carlo forums, or more general classic car forums, often have members who have tackled similar issues and might have a diagram or be able to point you in the right direction. Be sure to specify the engine size (305) and any relevant options when searching.
* Chevrolet Dealer (unlikely but possible): While a long shot, a Chevrolet dealership *might* have access to old service manuals or parts diagrams. It's not guaranteed, but it's worth a call to their parts department.
* Local Mechanic: A mechanic specializing in classic cars might have access to the diagrams, or at least the expertise to trace your vacuum lines if you can’t find a diagram.
Important Note: When using a vacuum diagram, pay close attention to the details. Small differences can greatly impact the system's function. If you're unsure about anything, consulting a mechanic is always recommended. Working with vacuum lines incorrectly can lead to damage to your engine.
