Ok, I was able to find the two of them that are in very good shape. I've got a collection of 5 LOL. They are both for V-Belt applications. I don't have any "newer" stuff anymore, I tossed the serpentine alternators last year. I have the sinking feeling that those are what you needed.
1: Delco DL7127M 10SI 63 amp alternator from Autozone. Clocked at 12:00.
2: Delco 1100217 12SI 78 amp alternator (they stamped over the amp rating on the unit but I looked it up and it seems to be 78 amps.) Clocked at 3:00.
Have a look at this and let me know if either fit the bill.
