I agree with wheel vintiques. You can also cruise the for sale ads here and other mopar forums for them, but they will be used.
I would reconsider BFG tires. There a plenty of stories on their quality. My last set, with very little mileage although older, separated in the tread down to the cords and was within a few miles of blowing out. Many guys run them, but many guys are also now choosing other brands (MT, Cooper Cobras, etc).
