Hello, I have a 498rc2, and some time ago one of my kids unscrewed the locking lever for the ball head. This caused _something_ to come out, as putting the level back in, and screwing it down no longer locks it. It looks like the end of the screw/lever is hollow, and something else went into it.
I've tried contacting Manfrotto via their email form at: http://www.manfrotto.us/Service/Spare+Parts
on four different occasions over the past few months, and have yet to hear a reply back. Does anyone know where else I might be able to order parts, or an alternate way to get a hold of them in order to replace a part?
