Just looked at my parts book for the 1930 model A,B, and C and it gives the same part number of 123037 as Herb has found fit the 1929 models, even though they had different transmissions, which implies these parts may also fit the 1930 cars as well. I’ll bet there are several members cars that would benefit from the replacement of that part, as it’s unexpected release can be a real safety issue. Still interested in buying one if they become available. Thanks for your efforts on this project.
