Alternator rebuild parts

Does anyone know of a place in the US that can sell me all the necessary alternator rebuild parts for a 1996 Legacy Outback (EJ22) (bearings, rotor, diodes etc.)? It seems that electrical systems for vehicles in the US (Indiana) are different from those (from Japan) here in Sweden. Hence, me NOT being able to get the correct alternator for my vehicle (see link on New alternator/uneven idle). My options are to buy a heavy alternator in the US and ship it here. I then have an issue with the core charge-expensive shipping etc. The other option is for the guy that sold me the new (rebuilt) alternator here in Sweden to rebuild the original with parts that I find in the US. This sounds cheaper and better from a logistical point-of-view.

Any advice?

Also, if I need to buy an alternator in the states, where can I get one that is good and inexpensive? It seems that Subaru only sells rebuilt ones as well nowadays.

Thanks again for the advice beforehand!
