What trim piece is this ???

I've had these trim pieces since I got my poncho (51) but have no idea what there for, how they attach or even if they're complete. The only profile they seem to match is the front top curve of the doors, but I'm at a lost for what they are or do.

If anyone knows or has a picture of how they mount, it would be greatly appreciated !!!

Thanks much !
