* Online Classic Car Parts Suppliers: Websites specializing in classic car parts are your best bet. Search for sites like:
* Classic Industries: They often have a large selection of Mopar parts.
* YearOne: Another reputable supplier for classic American cars.
* Ames Performance: A significant supplier of Mopar parts.
* EBay: While you might find individual wires or sections, you might get lucky and find a complete harness. Be cautious and check seller ratings carefully.
* Specialty Mopar Parts Suppliers: Search for suppliers that specifically cater to Dodge and Plymouth vehicles from that era. Smaller, specialized shops sometimes have parts that larger retailers don't.
* Local Auto Part Stores (Long Shot): While unlikely to find a complete harness, some larger chains might have some individual wires or connectors that you could use to repair your existing harness.
* Junkyards/Salvage Yards: This is a potential source, but requires significant effort and luck. You'll need to find a 1975 Dodge Dart in reasonably good condition and hope the harness is intact and reusable.
Important Considerations:
* Harness Condition: If you find a used harness, carefully inspect its condition. Brittle wiring, corrosion, and damaged connectors are common issues in older vehicles. A seemingly complete harness might require significant repair work.
* Correctness: Ensure the harness you purchase is specifically for a 1975 Dodge Dart. Variations exist between models and options (e.g., A/C, power windows), so getting the right one is crucial. The VIN number of your Dart will help determine the exact specification.
* Restoration vs. Repair: Consider whether you want to completely replace the harness or just repair the damaged sections of your existing one. Repairing might be a cheaper and less time-consuming option if the damage is localized. A professional auto electrician can help assess the situation.
Finding a complete dash harness might take time and effort. Be patient and persistent in your search. Start with the online suppliers listed above and broaden your search from there.
