First fitting of the forward baggage floor reveals a significant gap between the aft skin and the baggage floor. The skin at the attach point has no support, it is free to do whatever it wants, which is not what I want.
Cut a length of 1x2 to force the aft skin to the baggage floor, so I could locate the holes for the nut plates require to attach the floor to the after side of the firewall, as well as locate the holes for the left side skin rivets, and right side angle.
90-degree angle drill is a life saver for locating these holes next to skins, etc.
