I never try to totally remove the label. I just peel back the upper corners to expose the two screws. If you are careful and do not bend the label back sharpley, it can be hardly noticeable that it was repaired. I always leave the screws out so that future work does not risk more damage to the label.
To peel back the corners, I place a drop of UnDu (the solvent heptane) on the corner, a carefully work a razor blade dipped in more UnDu under the corner. The UnDu causes any adhesive to temporarily forget how to stick.
Usually the corners will stick back down just fine. Sometimes you have to reglue them. To do this I clean off all the old adhesive with alcohol. Then I use some Elmers contact cement. You brush the cement on the label corner and case. Don't let it pool in the label-case seam. Let the cement dry, the press down the label and rub with a soft cloth. The cement is neoprene rubber based and any excess rubs off.
