[WANTED] Prestolite Hi-Tone Horn for 1970 Duster 340

[340LJ]

I have a prestolite Lo-Tone horn in my 1970 Duster and rather than buy an aftermarket "sparton" set, I would like to just find a Prestolite Hi Tone to go with the Lo-Tone I already have. (I like having the adjustability on the bracket) If anyone has one they would be willing to sell or knows where I can find one, would be greatly appreciated. Would help button up my engine compartment.
