How to get a surface gui position in world space?

incapaz this does have to do with scripting. I want to find the position of a gui in the world space using scripts.

So im trying to make a game end surface gui where as you view what you did that round and as you scroll down the list little particles come out from the frames.. However I have no idea how to do this, I could position them perfectly as I am using UIGridLayout on a scrolling bar. But if the player scrolls ever so slightly the particles could be off. Is there a function to do this? Or do I have to be hacky?
