More transponder support work, maybe slightly more progress, I am tentative about how close to the left side skin that it will be as the wiring ends will need a certain amount of room (roughly 3.5") while the closer it is to the center of the panel, the more "other" things it will interfere with. But I have the hinge points set to where the support is allowing the tray to move and sit without adding any twist to the tray / transponder
