There may or may not be a triangular shaped brass tag attached to one of the 4 screws that holds the airhorn to the float bowl. If there is, it will have a number. If not, you should contact Jon (CarbKing) on Monday or Tuesday at The Carburetor Shop: https://www.thecarburetorshop.com/Orderinfo.htm
He will be able to tell you what you need. Good luck!
