Interior rattle

[Lawdawg]

Has anyone ever experienced a rattle from within the Z's interior? I'm picking up a slightly annoying rattle on bumps or uneven pavement. It sounds as if it's coming from the passenger side dash, door, windshield, or roof area. I have checked every possible nut, screw, and bolt that is accessible from the interior of the car and have found nothing. My next step was to start removing the passenger door panel and dash pieces, but I wanted to check here first. Thanks in advance.
