Part 585 and 586 appear to be the same item (Upper Wash Arm Water Supply Tube). Part 586 is not the Upper Wash Arm Water Supply Tube. It appears to be another part.
ANSWER Hello Brent! Item is the cone docking. The manufacturer has discontinued this item and now only offers items 585 and 586 as an assembly, part number WD12X10113. Thanks!
