“stacking kit for washer WM1355HW I was advised by LG personnel and other professionals that the stacking kit I needed was the WSTK 1. This is the WRONG kit! I ordered it, unknowingly, and when they brought the washer and dryer to stack it, found out it's for the full size washer not the one I bought!!! AAAAhhhhh... What is the right one? There is another one I've see listed in some places as RSTK1. Is this the right one? Please help!”
