Your starter went out on your 93 G20 can you replace it with the hitachi or do have to use Mitsubishi?

The 1993 G20 could use either a Hitachi or Mitsubishi starter motor, depending on the model. The Mitsubishi starter motor is the original equipment (OE) part, while the Hitachi starter motor is an aftermarket replacement part. Both starter motors should fit and function properly on the 1993 G20.
