What did you do to your '67 today?

[Lfino]

Pulled the high and low horns off today. Put power to them. Nothing. Ran the screw in and out. Nothing. Tapped them with a hammer. Nothing.
Filled them with PB Blaster. Letting them soak overnight.

Looking good.  Nice to have a helping hand.

Isn't there just a thin type of flap or something that gives the horn it's activation?
I'm pretty sure they're very simple inside

[Lfino]

Yes. The horn is pretty simple inside. Just can't get to the inside. Rivets.
Today I took the screws out that control the vibration. Filled the hole with PB.
Tomorrow I'll probably hit it with 18 volts.

The horn, when supplied by 12V,  has a normally closed set of points that energizes an electromagnet to pull a metal diaphragm back. As soon as the diaphragm is pulled back far enough the one end of the points attached to the diaphragm loses contact. This off/on happens very quickly resulting in the diaphragm vibrating.
The screw adjusts when the points make/break.

Looking good, Jon.

Make sure the horn is grounded when testing it. There are several companies that can rebuild them with the original style rivets. "Hornworks" comes to mind.

Restoration of Mustang horns by a outside service maybe the only practical way to save the exact same horn that came off your car (if you are absolutely positive it has not been replaced) . However the cost of restoration typically far exceeds what you can typically still find used working Mustang horns for. The Horn works for example https://www.carhornrestoration.com/  is 249.00 to restore your pair of cores (on sale for 219.00 for june and july). FYI given the time and materials it can take to restore a Mustang horn I don't think the costs in the example are unreasonable just that there are less expensive alternatives . At least for now.

Gary at the Horn Works did my '67 horns. He did a great job and they work perfectly.

Sent #906 off for new paint on Monday.  Had it bead blasted last month, did some sanding on it per the painter and then bombed canned it with primer to keep the rust off until the painter gets working on it.  Will need a new drivers side lower rocker panel and the front end has had damage years ago.  That will all be repaired along with new radiator support and torsion bar support brackets.  I'll see it after the first of the year.

Don't say the C word, but these folks have the rebuild kits available...
