This sounds like a stupid question but I can't find the horns

[egorny]

Just purchased a 76 GMC short bed in real good condition.
Runs great, no rust - came out of Texas.
The one issue is I can't find the horns!  Maybe it was an option - just kidding.
So where are the horns suppose to be? Is there a horn relay hidden someplace.
A picture if possible would help.
Thanks
Ed

yup, as far as a relay my truck has one under the dash somewhere but i couldn't tell you if this was factory or someone else's handy work.

Just on the inside of each headlight.
