I am putting my dash pad on and noticed that the screws that secure the dash ( plastic ) to the pad only have slots for the screws but no previsions for nut clips. My question is since this is a repop pad were do the 4 screws at the top of the dash get attached to since the pad only has 4 ovals, with no kind of backing to secure nut-plates. I don't see anyway to drill the metal dash that the pad covers to attache the screws............HELP....Thanks..............Mark
