Attention: TDR Forum Junkies 
A while back I was tryinig to source out where to buy the Hadley horns seperately. Well, they can be purchased directly from Hadley's distributor, Components Direct . They are in Illinois. They have a toll free number 1-800-875-4488. You can order any product that Hadley sells, including individual horns, parts and mounting brackets. They are very helpful and friendly to deal with as well. I thought someone else was looking for them too, so I though I'd let you know.
