With the introduction of the first six cylinder engine in 1929 the horn bracket location was between the two-hole base carburetor and intake manifold.
The location was changed with the re-designed 216 cubic inch six cylinder in 1937. The attaching point actually was cast in to the intake manifold during production. There was no longer a steel attaching bracket that often broke when used continually on the country’s very rough roads. The horn nose was now shorter but kept the same working parts in the rear.
