Here are the photos from my headlamp bucket. You can see that the screw has a different type nut. It is a metal nut with a flange that goes behind the tab and dog ears that turn down over the front of the tab, locking the screw in place. The problem with mine is that the dog ears are worn out and will not hold the screw in place. I have attached two photos of the two screws and nuts that still work ok. The other two photos are of the flange the nut and screw ride on. I don't see any way possible that the nuts available in the parts magazine would work.
