i fitted a range rover l322 roof spoyler on my p38 went on ok but had to drill holes in the top part of my tail gate fit with self tappers screws and fill the holes and paint but you also have to re root your wires underneth the spoyler for you high level brake light .and if your struts are not up to scratch you will find you have to hold your top gate open with your hand as you load it with shopping as its a lot heavier
