Found it! "Coerced" the alternator off after a good lunch (and a nap) and it was staring me in the face.
Now how to fix it.

The elbow appears to be bonded in originally. Wonder if I can rebond w/ something or should just replace the whole piece. Appears to be part 996.106.039.73 (#15) in PET. $200 from pelican and special order (so who knows how long it would take to get!)
