This winter I will overhaul my Delco Remy starter, so looked through my parts, and found out I had different versions.
When I take my starter apart I know what I need, but just wondering what the other parts are for.

I have looked through some old threads, and found out that there is a 9 and 10 toothed drive, but I have one with 11 teeth.
10 tooth will fit with 104 teeth flywheel, what flywheel will work with 9 or 11 teeth?

I have 2 different springs, believe the left one fit my starter (all 1925-34), the right one has bolts in other positions.
If I look at FS homepage the right one look like the spring on a 1934-37 drive, is this correct?

Drive in right side has 11 teeth, is it for a Chevrolet?
