Volvo 93 240 Wagon- Just recieved rocker panel trim section for the driver side. It's the long piece of thin trim that runs the length of the entire side of the car. Goesright beneath both doors from quarter panel to quarter panel. Came with 13 clips, but I can;t figure out how to install. I was told that you attache the clips to the back of the trim peice, then push into the holes in the car. Makes sense, but I can't see how to attach the clips to the trim. Probably my ineptness. Can anyone help?
