You don't have one fitted, but if you look at the pic, right behind the ds rubber boot are 2 holes, 1 is a threaded hole other is purely a locator hole no thread, then look on the wishbone there are so 2 holes, 1 is a locator hole & other is to screw to with a nut to the threaded part of the lower part arm of the levelling unit.
Some 8P's only have the rear sensor fitted, year dependent.
