There were two kits available: A9738063 and A9738065.
I randomly picked one thinking they both went on the panniers, and turns out, it's one or the other. So the one on my bike is 8063, and the other is for sale.
They are two different part numbers as one would go to a retailer and order different tree ornaments for your tree -- they all fit your tree, and are different numbers in the catalog.
