I have a 15year old evenflo lullabye crib model # 78450 that we are borrowing from a family member and I need instructions on how to set up the side rails so that they will move up and down. There is an extra bracket that fits on the bottom and we can not figure out how it is supposed to go on the crib. Any suggestions would be great.
