Delco America, of course. is no longer casting 10si cases. So the rebuilders collect cores and some rebuild your old one. The "new" aftermarket cases/look-a-likes are cast in China.
Not always a given, when you buy a rebuilt one, whether it's a rebuilt Delco or a rebuilt China clone. Check Markings, PN. logos and vendor statements.
The Amazon alternator I linked says it's an ACDelco, country of origiin....USA. I would never paint or chrome one.
