Quick question - I've haven't got round to fitting my new undertray yet (my car came without one) but I have bought all the required fixings based on the parts list in post #30 above. Amongst the many fixings it lists 6-off Grip Pins, P/N 8D0 805 121, can anyone tell me which positions the grip pins are fitted in - its not clear from the diagram which are the grip pins and which are the panel screws.
