I installed a couple 55b6p and 1 65b6p. Used peerless SF650 for flat and Audio Solutions ASFM64 for a small amount of articulation. I don't know if your Sanuns mount will work. It looks like it may be a little too tall. The peerless mount worked great and I ended up cutting the arms and moving them down below the bump out on the back of the TV because it was in a high traffic area where you could see the side of the TV. I left them unmodified on another TV and it looked fine.
