rear).

indicate that these parts were never used but apparently Ford experimented with
this type of steering for the Model T during 1910 and 1911, expecting it to be
used on the 1911 touring and roadsters. The left-hand engine pan (T-2367) was
also designed for this type steering. Elsewhere in the Archives records are notes that worm steering, as well as cable-operated rear brakes were used on cars shipped to Germany. Worm steering parts were listed into the 1920's; perhaps through the end of Model T production. | |
