Horn on my 72 just quit working.

The horn relay in my car is just above the kick panel on the drivers side. I have replaced it with no change.

I do not see that the horn has a fuse in my owners manual.

There is a horn relay on the firewall, about the size of a tater-tot. If you disonnect @ the horn you should be able to hear the relay click when you tap on the button. I not, bad relay or fuse.
