Hello everyone , I have a 59 500s i have bought side skirts and wondered how to fit them i have some clips that came with them but were in the centre as if you had to drill holes in the side of the sill , there are holes along the edge that goes underneath the car and there are 4 rubber oval grommets but 6 holes on the skirts , has anyone fitted them i bought sikaflex to stick the top part , but looking at them they need securing underneath too , thanks in advance
