If the set that you ordered is unmounted and in new and resellable condition, we can exchange them within 30 days. Please note that you will need to cover the return shipping. 

Go ahead and open a ticket and when you do, please send us some pictures of the mud flaps in the original plastic wrapping. If you already opened them, you are not SOL...we just need a picture of both the front and back of each flap and we will begin processing your return.
