They make at least a couple of wheels - a 14" and a 15". I think Keystone makes a wheel for it as well (been a while since I've looked - don't have a 6-cyl anymore)
I'll have my wheels up for sale in a couple of weeks. I actually have 2 that I could sell now. The are the American Racing Outlaw IIs in 14x7s with yokohama 195/75/14s. But if you are looking for anything else, the bolt pattern is 4 on 4 1/2.
