Product review (5 stars): Sturdy W10321304 part.
This fit perfectly in my Whirlpool side by side.  Not only that, maybe because it's new it feels sturdier? I ended up purchasing two.  I am very happy with my purchase. Solid replacement part for part number  W10321304.  It's wonderful to have a non-cracked, sturdy, shiny part after making do with the cracked one. Highly recommend!
