I'm trying to figure out the part Number for the load floor panel (the hinged deal that folds up when rear seat backs are up) for my 2007 Nitro SLT. I ordered a 1QD58XDVAA Filler being sure that was it and it turned out to be the Carpet piece that snaps on to the part I need. The IPB is not very clear on this. Can anyone help? I have a light grey interior. Also I have the sliding load floor if that is important.
