I got myself a second hand 9000 rear spoiler part no. 11600582 which is inscribed underneath, does anyone out there know what size nuts you need to bolt to my 9000cse (1997). It is a painted fibre glass type not the rubber type found on most 9000's. Alternatively I could go to my local halfords with the spoiler and see if they find me fittings. Also is there anything I need to know before fitting spoiler.
