Product review (5 stars): Perfect fit...
When the folks moved out of the house we just bought they pretty much took a lot of stuff that wasn't nailed down including the pan reflectors and oven racks in the stove.  Looked these up on the Whirlpool site using the range model and ordered.  They're a bit pricey but worth it because they are nice and heavy and fit perfectly.  They'll obviously give years of service!
