I have looked everywhere with no luck, I sure hope someone can help. I'm not sure what this piece is called but there are about 4 or 5 metal pieces that actually screw into the inside edges around the rear window. These pieces I'm assuming are what possibly some type of trim or the headliner attaches to?. I'm not sure as my 69 chevelle was pretty much stripped when I bought it. I'm missing one of the above pieces and really have no idea where else to turn for help.?? Hooked up with a couple of folks from this site about year ago but never heard back.
