Well you don’t want anything is a bad stress.
Believe it or not the package tray helps as well as the wooden belt rail
The lower top brackets add strength to the corners
The lower triangular brackets have a lot to do with the door post stabilization
You do have the upper panel and lower panel for the rear body in place. When correct those should dictate the span on the deck lid opening
