My sister in law works for Jostens and I had this ring made through her. It says W-30 on the other side and the year of each of my car’s is below the GM logo. She is willing to customize with 442 or Cutlass S as an example. This ring cost $300 Canadian or approx $250 USD. Feel free to contact her directly at Annette.vandekamp@jostens.com if you are interested.
