BTW, NEVER store one of these valances in this bottom side up, position especially when the weather gets cold. If you are going to work on it in this position, make sure you have something under both signal lamp pods to support the outer ends. Otherwise that crack in the bottom will spread right up to the top, and the valance will break into two separate pieces.
When I stored mine, I use a bunched up, old car cover with a higher area in the center, and I then placed the valance on it with the outside, facing up and the entire length of the valance fully supported by the soft cover..
You have a very rare example there that doesn't have one of the upper mounting bars broken.
