One other thing: I built a cradle for the boom (you can barely see it in the background of my photo) to support the boom and reduce twisting motion of the wing since the panel is part of the structural for the aircraft. Also. Supported the outer portion of the wing with large cushion (like a couch cushion), a piece of plywood under that, all held up by a jack like used to lift the aircraft for a gear swing. There are stringers in the underside of the panel that can bind and hold it down with slight twisting/bending of the structure. I found dropping the outer support jack an inch or two relived some compression jamming the stringers in their recess. After insertion, raising it back up to get things lined up. A little movement is all that’s necessary. Not using the boom support allows twisting complicating the removal and insertion process and it was my observation that just fractions of twisting or bending made things tough coming out or going back in.
