Car is a 73 with 2 horns up front. Horn on the right side (passenger) has died.
Is the horn on the right side the hi tone or low tone? Dont know if this helps, but # 614/615/681 is on the backside. Thanks for the help. Ed |

Frequency should be indicated on the horn.
- 914 635 103 11 is 335Hz - 914 635 104 11 is 400Hz I am pretty sure I have spare ones if you are looking for used ones. |

QUOTE(Montreal914 @ Aug 10 2025, 07:17 PM)  Frequency should be indicated on the horn. - 914 635 103 11 is 335Hz - 914 635 104 11 is 400Hz I am pretty sure I have spare ones if you are looking for used ones. Can someone offer clarification on the frequency markings? I have been through several threads, but am not clear on how to distinguish. Does it literally have "335" or "400" on it? The back of my horns don't have that. This one I believe is an early horn since it has bolts instead of rivets. Best I can surmise, the "T4" is the indicator? Its mate would be "H3"? Can anyone confirm or clarify? Maybe this is not a correct horn?
