1978 horn contact parts

[asphaltburner]

Yo! The diagram I find in LMC Truck's catalog doesn't seem to be proper,...anybody have a picture of the parts for a '78 P/U's horn assembly in the steering column? Contact, spring, and plastic retainer in the turn signal cancelling assembly and the parts in the steering wheel,...contact plate, insulator, and cap. I'm trying to rebuild this assembly that had parts missing. The order of assembly seems incorrect in the diagram I have, and I'm still missing the conact plate for the steeing wheel. Ordering the horn button cap (horn pad) from Classic Industries this week,...mines unusable. Junkyard is my only other source of info. Thanks, Todd.
