I've had this car for a year now. Working on it slowly. Does anyone know where the horns mount? Can you upload a picture of the location. Thanks

 

Back in those years the horns were usually mounted in front of the radiator to either side and of course behind the grille.
There was enough room under the hood of those vehicles to crawl in and go to sleep !
Whichever side the wire from the horn relay came from was the side the horns were mounted on.

 

Great thanks.
