The rear axle nuts for a 2013 Dodge Dart are going to have a hex size of 32mm. These are slightly smaller than what the front axle nuts will be at 34mm. If You're going to order a new set of nuts You should search for the oem ones but googling the official mopar part number which iS6510524AA. You'll see that these nuts are very cheap to replace just costing $5 plus shipping for a new set.
