Query: Great sound, but the attachment hardware is anything but...

I bought this horn for my Mom's bike thinking it would be a nice replacement for her usual screaching screams to the neighborhood kids to "get the 'bleep' out of the way". The problem is that the hardware to attach the horn is not universal and therefore did not fit the new bike I bought her for Christmas. I attempted to retrofit but it obviously didn't work. I showed up at her house with the bike only to find that it had dropped off on the ride over and was nowhere to be found.Honk if you find it.
