Yes, that's the bracket. There's no evidence it ever had any felt material or 'fuzzies', so I concluded it wasn't a window anti-rattle piece. In your photo it's upside down from how I found both of mine, which had the large hole below rather than at the top. Many apologies to all for considering my question without photos. Colorado 68's photo shows the bracket I'm talking about. What's it for and how is it correctly installed?
