My meat drawer does not open and close correctly. I inspected the parts on the refrigerator and cleaned them, then checked for replacement parts here. It seems that I do not have part no.s AP3414591,AP3425863, or AP3425894 which are listed as linkages and a spacer. I'm not sure whether or not I need them as the cover top that serves as the runners for the drawer looks completely different than the one installed on my refrigerator (part no. AP3186177). So my question is, do I need to order all the "missing" pieces and the cover top, or are said pieces compatible with my current cover top?
