O man, it's such an easy fix. First of all when I looked at it, it didn't really look like the dust cap was separating. But then I started to move it and noticed it was hanging on by just a thread! So I just lifted up the top upholstered part of the rear deck to expose the speakers. Held that part up with my elbow, and put the krazy glue (prob gonna redo with rubber cement) where it needed to be, and then left something with a little weight on it to hold it down for a hour or so. Came back, snapped in the big rear deck piece, turned on the stereo, bumped a song, and by golly! perfect!
