Looking for a replacement H-D 105th Anniversary patch. Any ideas?

Have you checked on eBay?  I saw a few on there for sale.

You can try checking eBay, Amazon, or Etsy for replacement H-D 105th Anniversary patches. Motorcycle forums and Facebook groups dedicated to Harley-Davidson enthusiasts are also good places to ask. Sometimes, local Harley-Davidson dealerships might have old stock or can point you in the right direction. Happy hunting!
