Kind of a longshot, but I thought someone might have a broken pair hanging out.
Basically I bought a pair of d5000 here a few months ago, and the pair was missing a part of the attachment that hold the cup to the headband. It is circled below. I need the part that goes on top (the part where the screw goes into). I would go back to the seller, but as it was I was pretty happy to finally get them in.
