-Doug:

Yea, your four major examples match my understanding. I can't explain what those two "oddball" starters in your collection are, however.

Two comments on your list of the four major configurations:

- I have heard that some of the late mechanical clutche cars came with a 3 bolt starter. Probably still with a 105 tooth ring gear, 8 tooth Bendix, but the bellhousing and starter housing had the third bolt. (For extra points: Is this a "shoulder" bolt?).

- You note that the early and late 2 liters differ in that the former has a 130 tooth ring gear, while the latter has 131 teeth. You note that these came with different starters, but both have 9 teeth in the Bendix. You note that the early starter cannot be used with the late ring gear, but suggest that the converse would be OK. I dunno - I'm skeptical that these can be mixed in either direction without chewing up the ring gear eventually.
