I lost a trim ring while fourwheeling a few weeks ago. I have found two different widths, but don't know which one will fit my truck. It is a 1985 GMC Jimmy (Sierra Classic) with factory rally wheels. The two different widths are 2 13/16" and 2 3/8". Does anyone know which trim ring will fit my wheels? Or can someone with an 85 (or so) measure one for me. The measurement is with it laying flat on a table. My truck is in Arizona, and I am back at college in Colorado, so I have no way of measuring it. If someone could help me out I would greatly appreciate it. Thank You Harley My Chevy isn't broken, its just out of gas.
