Does anyone think this is the plastic rivet used to fasten the wood trim to the door panel? I've been having a hard time figuring it out, and it seems that nobody knows what it's called or where to order it. But This video looks like it might be the part!
A possible clue!!! Although, looking at this, once you remove the top, the bottom stays in the whole, so you screw into the bottom part with a small screw. Unless you can drill out the entire part, and insert a brand new one.
