I removed mine from a Clairtone 7978 while I had the box apart . Looked like it was super glued in place . I bought a piece of plexi glass from Home Depot and cut it by hand to size using a plexi glass cutter . Then recreated the lip that is glued to the body using a table saw . Kind of similar to cutting a dado but with a regular blade . Worked well and much cleaner than before . My original was cracked and yellowed . Message me if you would like pix .
