Hood Reinforcement for hood bumper?

[DJ_Baar]

This washer looking thing fell-off when I opened the hood today (picture). It appears to have come from left front corner of hood and would have contacted the adjustable bumper on that side. (Note I just painted underside of hood and it has paint, where it appears to have feel from now does not.) It appears to have been spot welded in a couple placed and matches location I took picture of with it. Nothing on right side of hood.

Thought I should ask here, if anyone has seen it, one of ya'all have.
