After looking over my truck this weekend to get some things working (horn was on the list) - I noticed that the physical horn was removed - that's just great

Another expense for something that should be on a vehicle when you buy it...
I need a working stock horn for my 69 blazer - not sure if it came with one or two horns, but I need at least one to get this working -
Anybody have a pic of where it mounts on the core/radiator support?
PM me with what you have to offer. I know somebody has one/some sitting around collecting dust...
Thanks in advance everybody...
