At the rear of the front fender there is a moulding that runs 6 inches or so up the fender and actually mounts through the fender itself..what is that piece called? The piece the mud flap attaches too??? I have called the dealership to order one and they say they have no part that meets that description....I told them I would take a picture email it to them but they say they cant do that.....I would just drive over there but they are quite a distance out from me...A part number, proper term anything would be appreciated.....I would have never dreamed something like this would be such a big deal! Thanks a million!

not sure exactly what piece you're talking about without looking at mine, but this site might help
