Front or rear?

For the front one all I did was use a razor to remove 4 tabs on valance that had no where to go on a non-se bumper.

Then it reuses the screws on the bottom of the side, and the pop pins in the front.

It is a little longer than the bumper in the wheel well so if you want to secure it there you'll need a spacer and drill a new hole in the wheel well.
