Hey there bucko!!! All ya gotta do is play "musical chairs" with the letters that's already on the back piece. I think it goes a lil somthing like this:
eclipse---->speelc
You have to flip the "c" around and connet it to the "l". And use a razor knife to CAREFULLY peel them off. When you take them off don't pull on them or you will "wrinkle" them. Good luck.... BIOTCH!!
