Integy REVO Brushless Conversion Mount

They seem to still make it

and at a decent price, though idk what shipping is because Firefox says the connection is untrusted when I try to checkout. I can't seem to find ANY reviews of that mount or even pictures of it mounted on a REVO. Does it just go on top of the stock motor mount? It says it works "in conjunction with any other brand conversion already installed." Not sure if that means to hold the batteries and ESC down or if you need some other hardware to mount it to the REVO.
Anyone used this before?
