The only thing you have to do is remove the stock black plastic inserts in the upper grill before you install the Street Scenes Grill. The stock grill is held in place with plastic rivets which you can cut off very easily. The Street Scenes Inserts are held in place with metal spring clips that have teeth on them to grip the inserts and the frame of the grill. The upper pieces are easy to install. But the 4 pieces of the lower valance are a little tough to get to. There is not much room to work. It takes a little time and patience, but obviously it is doable.
