Removing the Back Trunk Panel, in a Coupe... Options

[Coomer]

Hi,
I've nearly got my whole car sound-deadened using RaamMat(similar to Dynamat Extreme but without the logo and the hefty pricetag), and I've only got one bad rattle still. The very back panel of my trunk(where the tail-light bolts go in) rattles a lot, and it's not just the license plate on the back of the car rattling. I've tried and tried, but I can't figure out how to get this panel out of the car. I searched websites and looked in my Chiltons manual, and it doesn't mention it anywhere. I was wondering if anyone knows how to get this out, because it's really bugging me having a rattle there when I turn the bass up loud.
