Are you talking about the little plastic stand that you screw into the TV? It doesn't come with that?
Go through the checkout process. It asks you for installation options...stand is ~$150 extra forgot what the wall mount costs.
If I misunderstood what this option is in regards to, my apologies however I took it to mean the actual stand it connects to the bottom of the TV and rests on....
