A:Answer ZS, thank you for your question. After look at the part numbers, the washer and dryer stacking kits are not the same. The issue is that the holes with the washer may not line up with the dryer. If they do not, and I am not showing that they do not, then they cannot be stacked. I would not recommend stacking them as it does not appear they can line up. I am sorry.
