* Online classic car parts retailers: Websites specializing in Buick parts, classic car parts in general, or even those focusing on 1960s-era vehicles are your primary resource. Search using terms like "1965 Buick Riviera headlight motor," "Riviera headlight actuator," or "65 Buick Riviera headlight mechanism." Be prepared to compare prices and shipping costs.
* eBay and similar auction sites: These sites often have individual sellers offering used parts. Carefully examine photos and descriptions to assess the condition. Remember that used parts carry a risk of further failure.
* Classic car parts suppliers specializing in Buicks: Some businesses specialize in parts for specific makes and models. Look for businesses that explicitly focus on Buick parts or even just classic Buick Rivieras.
* Classic car forums and online communities: Forums dedicated to Buick or classic car restoration often have members who might know of sources for hard-to-find parts, or might even have one for sale themselves.
* Junkyards (auto recyclers): A long shot, but some junkyards might still have a 1965 Riviera (or a similar-era Buick with interchangeable parts) sitting around. Calling them directly is necessary, as online inventory isn't always comprehensive.
Remember to specify "1965" when searching, as headlight motor designs can change slightly from year to year. Be prepared for the possibility that finding a new, NOS (New Old Stock) part will be extremely difficult and expensive if possible at all. A rebuilt or used part might be your most realistic option.
