The steel distributor drive gear with the internal keyway is used on the 1924/'25 REMY 950-B generator,and is retained by a slotted circular nut.
The steel distributor drive gear for a 1923 Chev with the AUTO-LITE generator,has no spacer as such,as it is machined as part of the gear,and the gear is locked to the generator shaft by a solid steel drive pin through this small extension of the gear.
Both drive gears turn the brass distributor at the same speed as the gear ratio is identical.I may have a matching set of either very good 2nd hand gears or a set of either NOS or NORS gears to suit the distributor used on the AUTO-LITE generator.
