I need instruction on reinstalling the rear cup holder

[Darkmann]

'02ML320: I could see this coming a mile away and finally my kids managed to dislodge the rear cupholder. I haven't looked at it closely but seems like nothing is broken. The only loose parts are two circular drums/rollers, each having a wound metal spring around it. There is no indication as to the orientation of these springs or the drum assembly. Anyone have instructions on how to put these back in there, any pics? Thanks. Oh, BTW, can anyone give me a heads up on what they'll be breaking next??? Love them, but sometimes, boy....
