Floyd Rose question

I have a Floyd Rose tremolo on my Ibanez RG 270. There is some thing that goes on the bar where it connects to the bridge. I think I need that. All's I know is there is a giant hole where the bar would go. I can almost slide my pinky into the hole, it's so big. It's just a hole, and that's it. What do I need to get to start whammin' again? Help me out here.

If there's something to screw , then it's the bar holder , how did you lost that ?
Or is it just the washers ?
I think you can find both in a nearby Guitar Shop ... Take your guitar with you to make sure that everything fits.

Some bubble gum and a screwdriver will work in a pinch just hold it together with duct tape :)
Nah seriously post a pic and I'll tell ya what you need.
