Whirlpool Refrigerator>Need help finding the right part> Please help

Hello.
Trying to see what part I need to get for the posted picture.
Diagram for dispenser front. I thinkI need part #11. However, I think the plastic nut is attached to Part #1 and is not a part of #11. The ice door will not shut all the way. This is due to the Screw not haveing the right nut to hold it in place.

thanks
