Vesa Mount for Optiplex 3060 Micro

Does anyone know which Vesa Mount is compatible with the Optiplex 3060 Micro ? Basically want to mount it on the back of the VESA holes on the back of a monitor, non Dell ?

I have seen the one for the 3050 and they are basically the same size just wondered if thats the one to use. On the product page for the Optiplex 3060 there is a picture of one but no link to which it is !
