I have a Delco horn I just bought and it is a 6 bolt pattern, I think I need a nine bolt. If I put this on and have it Judged someday will points be taken off? If I need a 9 bolt where do the missing 3 holes go? I have a shop and can drill them if I know where they should be placed. Also do the terminals go up or down when mounted. Thanks Rod

Borrow a 9 screw horn and copy the pattern. Note that the holes in the outer face are square. Find a fabricating shop that can punch the square holes for you. There is no other differences between the 6 and 9 screw horns.Be sure to visit;

chief348@juno.comSend me an email to the attached link in this message. I can send you photos of a Horn I just converted. I can also send a photo of a Horn with all the brackets and hardware attached that I was just ready to mount on a bike. The harbor Vintage idea is a great one and that will give you the bolt pattern you need.

When looking at the rear of the horn the terminals will be in the 3 o'clock position.

You didn't say you had a 6 bolt with a mounting bracket. That gets a little tougher. You are probably better off finding a 6 bolt horn without a bracket attached. The brackets can be removed by unriviting it but it is a real chore to rerivit the back on once the bracket is removed.

If you horn had a good bracket on it trade it to someone who has a broken bracket. I have several.Be sure to visit;
