Hi, could someone please assist. I need to replace the “Hi” pitch horn on my 70 Shelby. I realize this is a standard Mustang part however I am wanting an original horn not a reproduction, looking on eBay and also various Mustang parts stores it seems that only reproductions are available. I understand from reviews that these are made in China and are of poor quality..? Are there any places I could try to source a good used original working horn or should I drill out the rivets and attempt to repair the one I have. Appreciate any help.
