Rear deck lid problems

With the oval section being tipped down there is a small problem with the way the rear deck lid fits. It doesn't close, and if I remove it from the hindge and set it where it should be I seem to have a little over an inch gap from the top of the deck lid to the bottom of the oval section. I have looked at this for awhile trying to figure out the best way to fix this with the least amount of cutting and welding. I have come up with something but will wait to share until I'm done and can post some pictures of it.
The shot with the CUT lines on it was a thought but that cuts into the rain gutter in the oval and was not a good idea.
