Help with Floyd Rose

Hey guys, i'm new here. So here's the deal, I bought a MIM Richie Sambora Strat a few months ago, but the guy who sold it never found the whammy bar, so I have to buy a new one, but I don't know which one should I buy because as far as I know there are two types of whammy bars. So here I have a picture for you, the unit is a Floyd Rose II.
