Thanks for the replies and comments!
Mike - I did a cutout for the bag door brace after that photo. That was one of my minor foul ups - thought I knew which side to set up for that, but got it wrong and drilled a hole for a screw right on one of the rivet holes for the brace. Fixed it with a small piece of scrap behind the tab for the brace flanges.
Mistakes are an opportunity to learn.... getting my money's worth there.
