This is the back of the light (this is the old unit) the black around the torx screw is just some kind of felt washer. I believe the rusty bits that have fallen apart are called U nuts after googling, I know it’s a T20 but I don’t know what thread it would have. It’s bloody annoying, I just presumed all I would need would come with the new fitting.

 

Try a local auto parts store, they should have a selection of these to chose from. (You can find assortments on Amazon, but you don’t need that many.)

 

Just a quick update, I went to Halfords of all places and bought a small packet of assorted U nuts. Used the size needed for the T20 torx bolt and everything is good. It’s just a warning for anyone else removing or changing this light fixture, my U nuts were corroded to nothing, so may be a good idea to have some of these before starting the job, they were less than a couple of quid. Thank you for all the advice 👍

 

Hi georgekale, would you happen to know if there is a gasket that goes between the deck lid and the spoiler?? ( 08 XK coupe) Thank You!!.............r

 

You might want to tag @georgekale correctly to maybe get his attention, as I think he sold his X150 several years ago, and probably doesn’t keep up with this forum anymore.
(This post will have tagged him.)

 

Right on. I sold my XKR about ten years ago.Sorry can't help you there.

 

No, there is no gasket from spoiler to deck lid.

 

Thank you for this! Would anyone have a pic showing the location of this diode pack on a 2013 convertible? Is it in the boot lid somewhere?
and a part number if possible?
thanks
Alan
