Yes I did. I have moved the horns up inside the space between the grille and the radiator. They are bolted through the same holes that they were mounted in underneath so instead of hanging under the tray they now sit on top of it. There was enough length in the wiring to allow this without making any modifications. There are several holes around that area that would lend themselves to fitting the horns if you would rather they were under the car. Unfortunately, I didn't take any photos when I did it and it's not possible now without taking the grill off again.
