Have you installed it yet? It really looks good!People act like fvking kids about ****.Some people need to grow up I'm sure you got a box with the part number on them.
Here is the part number for the shift assembly, I don't think you will be able to buy knob by itself, as I get more part numbers I will post them.
HL3Z-7210-HB
I was able to remove the knob form the assembly so that I could install with my orange and black leather boot. Its very simple to get the leather up and remove 2 Phillips screws to remove the knob.
