Is the only difference in the fenders and door skins with the Aero package and without the brackets for the moulding to clip to? I`m wanting to get some door skins to bond the tapered mouldings from the Ausfiero style scoops to. Also, the small pieces that go on the fenders. From what I have seen in pics it looks as if the non-aero parts would be better to use as they have no holes for the moulding that goes above the rockers. That way I wouldn`t have to fill in the holes, just start with a clean slate.
