One of the more asked questions on the 1941-46 GM trucks is regarding horn contact parts. Most have been damaged over the years and new owners are unsure how they were originally assembled.
Below, is a diagram from a 1940's GM Master Parts Catalog and gives an excellent view of the parts used in the assembly.
Most items are currently reproduced, including the upper bearing, rubber bumper, cap assembly, steering wheel, 3 finger horn cap retainer, and internal cap spring.
