ordered mine from Nippy Normans also, Easy to fit, just had to fold one of the two supplied thin metal mounting strips in half to server as something solid for the horn to bolt onto; the stock rubber bushing and washers dont leave enough space to screw the mounting bolt on.
Horn is awesome, works flawlessly and is very loud, had occasion to use it about a month ago to warn cager who looked about to turn into my lane and he heard it loud and clear, he kinda jumped in his car giving me the impression it was truly loud enough to be effective. Give it a go, total install time 15 mins and that includes taking off the old one removing the rubber bushing and other pieces, folding the metal strip in half and putting the new one on.
Have a pic in my album if u wanna check it out.
