hey mate you gotta acess the garnish from inside the boot. there are a couple of screws but be gentle cause if u break a clip it wont sit flush against the boot and you'll get water inside the garnish. i have & now i have a headache lol
I don't know about the Stato but their 8mm nuts theres 4 of them I think. The garnish also keeps your boot tailights flush with the car, the tailights have a clip on the end of them by taking the garnish off these will look pretty ordinary if you arn't replacing it.
