After cleaning out the refrigerator area removing crisper frame an tray, transfer hardware to new frame. Transferred hardware includes faceplate (lift rear edge with screw driver), crisper humidity sliders (slide to one side then release locking tab, and a long metal support rail (slides out from one side). It's easy to miss the support rail and the structure is weak without it. Also in hindsight I should have ordered replacement humidity sliders as well.
