Do you mean the "Defender 90" (or 110) sticker?
Make the 90/110 part about 4cm above the rear fog lamp and the "D" 4cm from the left edge of the panel.
The oval "Land Rover" badge is fitted above this sticker, in a central position 4cm above the sticker.
Although l stuck mine an a bit higher up. Too high and the spare wheel can hit it when you open the door.
There, now who says l am not a Land Rover Geek.
