Considering that I might never find the missing piece, and also that if I did, I might be able to glue it in place due to it's shape, I decided to glue the 740.7 pieces that I posted about [id=467674965;here] and [id=467674797;here]. There is another tiny sliver missing from the wire groove that I hadn't noticed, but this will have to do until I find one intact. :)
