I've been conversing with another user offline about his starter.
That lead me to look again at two detail items about early (65-68) starters. I included 68 since they appear to have the nose cone and other details in common with earlier starter, but differ in the barrel encoding and drive cover.
After viewing the starter, that appears original, from my 65 A-code it appears I've made a few assumptions that may or may not be true. See first two pics of this filthy beast.
First, the long bolts that go through the bush holder to the nose cone.
My 65 has flat, no name or physical marking bolts with built-in washers/shoulders.
Later bolts have the inverted cone or look like the ends have been drilled.
The early Ford starter (somewhere in the 62-65 time frame) I used as the basis for a lot of parts in my 67 starter have the drill style bolts.
Any old stock starters out there that validate a date change or perhaps this is simply a different vendor? Maybe the drilled bolts are rebuilder-only bolts and I have this wrong?
Second, the brush holder. Both examples shown here are FoMoCo/oval circle holders. Never mind the rebuilder pop rivets in these examples. My 65 version, top, has only 6 tabs for holding the brush holder securely centered in the barrel. The other example shows 8.
