I'm searching for a replacement for 1 damaged wheel on my son's 2006 300C AWD. It has 6-spoke alloy wheels. A couple of local sources have told me that the wheels used on the AWD version are different from the ones used on the 2WD vehicles. At a fast glance they look identical me. Can anyone confirm that they are different? And can you tell me what the difference is and how to spot it as I go hunting at yards, swap meets, etc?
