Hi, had my front bumper off the other day (prodrive) And noticed these 2 parts on the shed floor under the car..
It might be coincidence, as theres a landrover also being re-built in the shed. But the bumper is re-fitted, and seems perfect. (screw in each arch, screw either end on the underside, 4 push button clips onto sub frame, and 2 push button clips between headlights) So i cant think where they could be from. Thought id better check though.
