I have a Simplicity 4 in 1 child's bed (Model #8676C) that I purchased from a friend. I want to convert it into the 'day-bed' however, the front railings appears to be too short to fit the length of the bed (in between the left and right railings). I do have the necessary parts, I just don't have the instruction book so have no idea how they fit together. Can you provide me with guidance as to how I can obtain a manual or at least directions on how to install the railings?
