Product review (5 stars): perfect fit
I had a missing or broken lower rack wheelie and took my chance and bought this for my GE Triton XL model GSD6660G03SS dishwasher.  Too bad I had to buy this and the wheel seperately which came out to be almost $8.  Worth it though because now the rack stays in placed.  And I ageed that this is better made than the original that came with the dishwasher
