To repeat from another post here today, I have a steel rim from my 06 2500 that I will be not be using as I have enough alloys and more to cover any future needs. It is free for the taking as long as I don't have to deal with the boxing and shipping. 92024 area code.
I doubt it was ever used with alloys that came on the van, but it was mounted underneath for a decade. No serious rust that a simple cleaning could not bring back. Good luck with your search.
