How can I fix my ice maker?

My ice tray broke off, and needs to be replaced. My question is this the only item I need to replace or is the more parts to it? I have the ice tray that broke off the mounting. The tray was jammed, and forced opened which caused the tray to snap off?
I searched on line and found the part for tray only - DAA 63-02284B and I also found - Case Ice Cube DA 61-03189A, but don't know if I need this last item also. I don't know what that pat looks like, and only recognized the Ice tray as to what I found broken, but do I need to replace the Case Ice Cube too to attach the ice tray?
