I looked for 5 years to find the correct one for my 66. I apparently have a oddball. What brand name are they? You may also need the diameter too. Almost any hi note horn will work but it may not mount correctly or sound right.

My duster has hi/low horns and I guess I had no idea they are hard to come by. One more thing I'll check the yards for when I go. Thanks for the heads up.
Be careful when purchasing replacement horns an ebay. I bought a couple that were original but did not work. Threw them out and bought electric air horns as a replacement. They are louder and people move after I am cut off and blow them as I hover around their rear bumper!
