anyone have any idea how much those two pieces of rubber cost? I rented a mb-d10 last week (bought a second hand one today :smile) and took off the rubber pieces to plug it in. My wife returned it, i forgot for some dumb reason to replace them and off they went to the rental company who now can't find them. Darn. Any idea what it will cost me to replace them? Can i only get them through nikon?
