Dont try to drill out the holes on the rocker panel, if even a single one is off by a few millimeters, and they will be, it wont fit correctly.
Doublesided tape works sspectacularly well along the top of the sideskirt. Adhere it to the car, then jack that side (put the jacks under the suspension not the pinch weld on the rocker panel since youre working here) and drill out the 6 or 7 holes along the underside of the rockerpanel for the clips. These are easier to drill since you already have a properly aligned sideskirt as a stencil.
