I just tried to install the polyurethane mud flaps on my 2004 WRX and I'm running into problems immediately when I try to install the front mud flaps. When trying to put in the circular clips that go between the fender liner and the wheel well the fender liner pushes the clips out of the way when trying to put the liner back in place. I'm not sure if any one else has had this problem. Maybe I don't have the correct pieces even though the packaging was labeled as the 02-07 flaps. If anyone has any info about this I'd appreciate it.
