Here are some places to look, listed in order of likelihood of success:
1. Repair Manuals: A factory service manual (FSM) or a Haynes/Chilton repair manual for your specific year and engine is your best bet. These manuals often include detailed diagrams and schematics, though they may not be called "schematics" explicitly. Look for used copies online (eBay, Amazon) or at auto parts stores.
2. Online Parts Catalogs: Websites like AutoZone, Advance Auto Parts, and Napa Auto Parts often have online parts catalogs. While you won't find full schematics, you might find diagrams showing the location and relationship of components within the engine. Search using your vehicle's year, make, model, and engine code.
3. Online Forums and Communities: Websites and forums dedicated to Dodge vehicles or 80s car enthusiasts (e.g., Dodge forums, Allpar.com) might have members who have scanned pages from repair manuals or possess other relevant diagrams. Posting a request explaining what you need could yield results.
4. Microfiche: Some libraries or archives specializing in automotive history might still have access to microfiche containing original factory diagrams. This is a less likely option, but worth considering if all else fails.
Important Note: The complexity of the schematic will vary. You might find detailed wiring diagrams (electrical schematics), but comprehensive mechanical diagrams showing every bolt and component are less common for the general public. Repair manuals are your best source for the level of detail typically needed for repairs or modifications.
