Just found GMC Truck Service Bulletin T-3-068 titled "KUDO HORN" STABILIZER, published Feb 15, 1956. I'll post it once our forum's attachment manager recovers from the latest update.
The 1960 GMC Master Parts Book does list the part numbers (there is a different left side part if you have power steering), but does not show the parts.
