1972 Canadian H-Code 340 Dart Swinger Special Resto - Finally started!

Your Swinger's looking great. Wish I was that far.
I do have another quarter panel install question if you don't mind. On the AMD quarter at the front corner of the deck lid, the gap gets really tight. I was wondering if I should make a slice in the top of the panel at the green line, and tap that metal over to open up the gap? then weld it back up. Any input would be appreciated.
Thanks
