Mark, When restoring the 97 DeLorean, we also noticed that this panel had delaminated from the original fiberglass. It also had some rust, but not as bad as you describe. In addition, to re epoxy gluing this to the fiberglass, we installed to 3/8 bolts through the plate to new plates below (after removing the headliner. ) This significantly improved the strength and longevity of the design.
