My 1967 Dodge Shop manual that covers PW does not show any internal assembly of the horn.
It does give the following adjustment procedure;
Quote
"ADJUSTING
1. Remove horn and bracket assembly, do not remove horn from bracket
2. Turn the tone adjuster with a suitable spanner wrench, turning it counter-clockwise until there is no vibration (sound)
3. Turn the tone adjuster clockwise, approximately 1/4 turn at a time until the tone has a clear mellow sound. DO NOT turn the adjuster while the horn is blowing
4. Adjustment will only clear up sound and cannot change horn frequency
5. Connect a test ammeter between the positive post of a 12 volt battery and the horn terminal post. Connect a jumper lead from the negative battery post to the horn base. Turn the tone adjuster to obtain a reading of (6) six amperes minimum to (8) amperes maximum at 12.5 volts
THE CURRENT MUST NOT EXCEED (10) TEN AMPERES " end quote
