Part arrived quickly. Removed all the food from the top shelf. Lifted glass shelf out of fridge (gave it a good cleaning while out!). Slid the old part out of the grooves and slid the new part on. Pay attention to the way you remove the part and make sure you put the new part back in the same. It would be easy to get this piece on backwards!! Replace the shelf back in fridge with the slots of the part piece ready to receive the drawer. Would not be fun to reload all the food on the shelf and find out the drawer won’t go on because the shelf is backwards. VERY easy fix!!
