Info needed: Ford CMP horn- diaphragm replacment or repair

[Ganmain Tony]

Jacques,

In my humble opinion, I reckon the damage will be negligible on the horns ability to function.

The hardest thing youve got in front of you now is getting it back together.

My experience is not extensive but I just pulled apart and repaired my F15 horn.

It has not functioned for years and looked rough when I pulled it apart. Simply gave it a gentle clean with compressed air, found a broken wire and after a couple of attempts soldered a broken wire I found in the internals.

It now has a nice, obnoxious blast.

Yours may be in worse condition but I am always amazed at the robustness of components of this era.
