Like perry said, any 14" wheels from Contour/Mystiques will fit. Just get the 4x108 bolt pattern. tirerack.com might have some cheap 14" wheels you can buy. I know they're starting to sell their 'winter packages'.
FYI:
I've got a set of the 14" steel wheels w/covers I need to get rid of if you're interested. brantleyiii@earthlink.net
