Bob-
On the stove I thought they were 2-6's and 2-8's it's just they looked small. Could be the angle of the pic that was taken.
What makes that DW MOL? What's the purpose of the switch that's to the left of the cycle dial. My parents had those racks in the first DW they had (but it was the push button rapid-advance model).With no upper wash arm and just that spray tower along with the bottom arm it did have some limitations for it's capacity.
