Panhard Bar "Do It Yourself"

[H. L. Chauvin]

FWIW on Model A swaying:

After witnessing complete failure of a few of the so called "re-built" Model A shocks offered today which were tested with the K. R. Wilson Tool method, (recommended in Ford's February 1931 Service Bulletin), it appears obvious if one has maladjusted shocks with totally reverse shocking action, swaying & bouncing a heavy engine unevenly can have an adverse effect on how the engine's weight is thrown around on a non-level highway.
