If you are still looking for the 20th anniversary hood decal the following is the part number :

Be advised this is one piece and comes with the left and right fender decal. When you realize that it's 3 decals (with no overlapping of decals to get the gold outline) plus quality is outstanding, it's actually cheaper if not the same price as aftermarket. Comes in a large flat box so decals are not rolled or distorted in any way. I love them on mine, once again quality can't be beat, and I love the inlay on the graphic.
