Horn question

Every car I've ever owned had two horns, one high tone and one low tone. On my 72 Scamp they are located beside the radiator on the passenger side of the car. They are mounted back-to-back with a jumper wire from the first horn to the second one. They are on their own little bracket together. Horns rarely go bad, if you can find a set in a junkyard they shouldn't set you back much. I would just about bet that Mother Mopar used the same horn set on lots of cars. Good luck.
