Alternator question. 1991 Lsi Convertable

Can someone tell me what my original factory oem alternator was?

Nipendenso or Mitsubishi.

VIN: JG1MR3360MK608483

1991 Geo Metro LSi Convertable

only real difference is if main wire come out the top of the alternator or the rear of it, the mitsubishi one comes out the rear, not the wiring plug, the large single wire, nipp is on top
