Removed the old bonnet insulation. As with everything on a 1986, insulation style is NLA - P#MUC9850 superseded to P#AWR4147. Cleaned the underside & carefully spread the gap between the framework & the skin, so an adhesive caulking (Vulkem) can be applied between. B-Quiet Ultimate to the panels & spots of caulk to make really sure the edges don't let go.
