just wondering

Farmer I don't think a 10 inch rim will work on the rear on a Dart Sport, just not enough wheel well. The rims you have for the front will work but those tires are really tall at 28.1 inch's.
If they did clear your car would look like a 4X4.
Use this site to check height of different tires and you can compare front to rear.
