Very simple. Removed the crisper, pantry drawers and a lower shelf to get clear access to the left broken end cap. The removal of the endcap was very easy. 2 hex head screws. The removal of the slide track on the endcap was also easy with the removal of 2 hex head screws. Installed the slide on the new endcap and reassembled all the pieces including the new pantry drawer. Could not have been much easier.
