Horn notes...which is which?

[HallenTi]

I understand that on my 1990 (and other years) there is a "C" and an "F" note horn. Currently, my driver's side horn works fine, but the passenger side horn just "clicks". I have removed the passenger side horn and attempted to empty out whatever is rolling around inside (rocks, rust, who knows), and I have also drenched it in WD-40® in an attept to free it up. This hasn't yet worked, so I am wondering which note this passenger side horn is to buy a replacement (would prefer a used horn than a new one). Thanks, Tim

Look inside the funnel or on the body of the horn...it should be stamped into the metal

I will do that...thanks for the idea!
