Hang the kit on the car, then use a marker to draw a line where the grilles hang over the kit. Then drill and place your rivets behind said line. as far as the skirts are concerned, use the rivets inside the wheel wells. once you paint and mount the parts back on the vehicle, the rivet heads should be hard to spot.

Two wheels or Four, I'm happy as long as the throttle is pinned.
