The significant change in the 2-Tooth Steering is the angle of the worm gear bearing. My February 1931 Coupe had the early design worm gear ) & shaft (before August 1931) that I updated to conform to the December 1931 Service Bulletin, Page 517. I did this because the worm gear & bearings available from "A" parts dealers is the newer design. The first change was made by Ford prior to August of 1931. The next change is explained in the Service Bulletin of August 1931, Page 481. Also see the National Judging Standards. There are several visible differences in the 2-tooth gear box castings.
