One new right rear mud flap for a 2009 Honda Element, only comes as a set of two, and I only needed the other LR side. List from Mr Honda for a pair is $53 plus tax, perfect if you only need the one side, said to fit only the 2009 and 2010 Element S/C, and part number 08P09SCV1B1R1.
If the ad is up, it's available, so inquiries asking "if available" and or without a phone number will be ignored. I don't text, and with limited time emails won't be answered without a contact number. So, a phone call is best for a prompt and accurate response. John at 53ZERO-477-71FIVE8
