Can you GP owners that have not ever removed their rear spoilers tell me if there are small divits on the black plastic piece on the back that correspond with the attaching screws.

I'm trying to get the correct amount of torque I should use on the mounting nuts. You can definitely tell where each mounting screw is by the way the black piece is not smooth all the way across.

I can't seem to find any good pictures of the rear part of the roof. There are a couple of MINI promo pics, but I don't think they accurately depict that area due to lighting and other factors.

I'd take a picture of mine, but it's at home at the moment.

Thanks,
