I don't have any pics right now because I'm not at home, but what are the bolts/screws called (on the top of the cage) that hold the piece of plastic in place that frames the windows on the full doors? There's 2 on each side and have a plastic wheel connected that you turn to unscrew them. I broke the plastic piece on one and need to replace it. Just not sure what they're called. I'm probably explaining this all jacked up, but hopefully y'all know what I'm talking about.
