I think an easy way to check was whether it had a duct or not. Mine didn't and had the rounder plug.
FWIW try swapping just the voltage regulator first, seems to have done me and a bunch of e46f guys the trick rather than replacing the whole thing

Have a buddy who works for Bosch in Germany and he says all they do is cut costs all day. I made the mistake of buying a Bosch coil that ended up lasting 3 WEEKS. Replaced it with an actual quality part and haven't had issues since. I would avoid Bosch at all costs.
I've replaced my 90v with a 120v remanufactured Duralast alternator. It was less expensive than the 90v with lifetime warranty. It's been a year with no issues.
Maybe this place, Maniac Electric Motors, has applicable parts (link). I don't have experience with them, but might try one of their rebuild kits.
Is Rein a good option for power steering hoses?
