Targa Top frame has rattling debris inside

That's strange because I don't see how anything can get in there. I wonder if one of the caps in the front lots one of it's tabs and that's what you're hearing in there. I'm talking about the caps that have the little piece of velcro on them and that fit into the anchors when you place the targa in the hatch area.

I believe the targa halfs are bonded together. So if it's something you can't get to from the outside there may be no choice but to remove the head liner then cut an access hole on the bottom side. Shake out what ever is in there. Then reglass a patch over the hole.
