1. Online Parts Specialists: Websites specializing in classic car parts or Pontiac parts are your best bet. Search for sites like these, specifying "1986 Pontiac Firebird Trans Am headlight motor":
* eBay Motors: Often has used parts, but be sure to check the seller's feedback carefully.
* Classic Industries: Focuses on classic car parts.
* Ames Performance: A long-time supplier of Pontiac parts.
* YearOne: Another well-known supplier of classic car components. (However, they may primarily deal in new-old-stock (NOS) parts and reproduction parts.)
2. Specialty Junkyards: While you've had no luck at local junkyards, try searching for larger, national or regional junkyards that specialize in classic or muscle cars. They might have a wider inventory. You can search online using terms like "classic car salvage yards" or "Pontiac parts salvage".
3. Forums and Online Communities: Join online forums dedicated to Pontiac Firebirds or Trans Ams. Members might know of sources for hard-to-find parts, including individuals selling parts from their own collections or restorations.
4. Used Parts Dealers: Some businesses specialize in sourcing used car parts. They might have contacts that can find the motor for you.
5. Rebuilding: As a last resort, consider having your existing motor rebuilt. This would require finding a shop skilled in working with older automotive components. However, this might be costly and time-consuming, but could potentially be more economical than a hard-to-find replacement part.
Important Note: When ordering online, carefully compare the motor's specifications to your original to ensure compatibility. Photos and part numbers are essential for a successful purchase.
