Avid Elixir 3 brakes

Hi,
I have a Rockrider 8.1 with rockshox silver recon forks, 160mm front and rear rotors. I am looking to upgrade to 180mm rotor on the front, but I can't find which adaptor I need to fit to allow the new rotors to fit.
Can anyone please help/advise which adaptor I need and where I can get them from for a decent price.
Thanks

I have looked at superstar and it shows all the adaptors but doesn't say which are one is for what.
My forks are post mount and avid elixir 3 brakes. I have been looking on the net for which on but to no avail.
Has anyone got any pictures or which adaptor I need?
