True we mutilated a portion of tunnel where the sight gauge goes that slightly weakened our panel, but it is not rigid enough for my liking.
We cut a 1"x2" furring strip and JB KWIKed it to a scuff sanded 3M 375 packaging tape stuck to module. This is only a temporary rib. It works well holding module in shape. Will bond a permanent, probably BID covered piece of Balsa once we know what is going in that area of panel. Can probably mount stuff to both sides! If going to do such a silly thing, might as well be thinking "synergistic harmonization"!
Cereal box template worked perfect for great fit in short order.
