The two jets differ, and I can't tell which one is which either (left and right). I can guess at the shape of the hole required.
Perfection would be if someone had a facelift bumper with headlamp wash holes and could do a 'brass rubbing' of the hole and position. Otherwise, any guidance on the position of the jets, and a photo to identify left and right would be a great help.
Failing that, if you have a facelift with headlamp wash, don't come to the Nano as some mad bloke will prise the jets out with a screwdriver.
