2004 Kia Rio 4d
I have a 04 Rio, I'm removing all the seats and panels to give it a deep cleaning. The front passenger seat has 1 bolt that I can not get loose. It's the one in back closest to the door. I believe it is a 14mm like the other ones except it looks different. (A nut not a bolt) I have tried every combo of sockets and swivels and rackets and breaker bars. I can't get a good grap on it and have ability to apply enough force.
