Can someone help me find where this goes?

[Alwayssideways]

I was taking off my bed cover and this popped off from some where. Can anyone tell me where this goes? I tried to find where it goes on the cover, or in the bed.

That's an end cap for the center hinge on the tonneau cover. Mine came off awhile back, I ended up using small nuts and bolts to bolt it back on. I think I had to drill holes in the washer that goes behind it on the cover.

I'll second that....had mine come off before too....
