Dear lazy web: I need an automovil expert

I need some assistance to purchase the right replacement for my car, if you can give me a hand it will be more than appreciated:

My car:

  • Kia Sportage GE ’97 (made in America)
  • Failure: flywheel

This is my flywheel:

the Flywheel have two sides, one with teeths and the other with a small squares. My teeth side is almost broken so i need to change the whole part, Googling a bit i found some vendors from the US that can ship the replacement but no one is able to confirm if the part is about both sides or just one of them. Its a very old car so they do not have full specs about each part.

Would you please point me to the right vendor  to purchase the whole part ?, any help is appreciated.
