I won't go into detail on the grille and existing horn removal. Photo 1 is the clean slate of the area behind the grille.



Next are the 3 horns I decided to use. A "matching set" from a 1965 Cadillac. I had to flatten out the mounting tabs to make them work with my locations.



The new screws are self-tapping ones from the hardware store. 2 on the driver's side and 1 on the passenger's.





Next are the horns mounted. I had to run ground wires for the 2 smaller horns, but the trumpet is grounded to the bumper.




All connections were soldered and taped.



I was surprised at how much room there was.



Then the moment of truth. The first trial sounding!




All in all, very satisfied with the results.

 

Very creative!
