Out of curiosity, what are you up to (if you don't mind me asking)??
As PontiacDad'* post indicates, it'* pretty straight forward. You need to be especially careful so as not to damage the plastic clips near the points beside the reverse lights. These aren't difficult to break. You can't buy them individually (I can't begin to tell you how bitterly I complained to GM over this). If they are damaged, you can end up with another path for water to get into your trunk (and we certainly have enough as it is). I searched and searched to find a used panel just for clips and not one had some that were any good. This means purchasing a new panel at $300.00 CDN+. If you don't absolutely have to remove it, I don't recommend it.
