Les Andrews:
"Two different starter motors and bendix drive assemblies were installed on the Model A. The two are not interchangeable. The early starter motor (Abell) was used from beginning of production until Oct 1, 1928. This starter had a 1/2" motor shaft. The later starter motor (Oct. 1, 1928 to end of production) has a 5/8" motor shaft. The early bendix drive has a special form of ten-tooth pinion gear and can only be used with the early flywheel ring gear. The flywheel ring gear changed with the change in starter motor and bendix drive assembly.

Dec. 20 1932 Parts Price List:
Parts lists show B-6384 as the only flywheel ring gear available but dealers were advising both starter and ring gear be upgraded.

The assumed 5/8" starter/Bendix was A-11350-C. A special service starter A-11350-DR was available for 1928 cars. One assumes this took the place of the Abell starter and was of Bendix pinion.

Service Bulletins:
Show a A-18475 starter as the Abell replacement assembly embodying a Bendix pinion for earlier ring gears.

So some care is necessary going forward.
