Success! This guide was very helpful. Here is a bit more info:
The LCD screen I ordered did not have the plastic frame. The original frame is easily separated. Push the LDC out of the frame from behind. This takes some force. Be careful not to break the frame. After separation, I removed the sticky material between them and replaced it with double sided tape. I first stuck strips of the tape to the inside edges of the plastic frame and then trimmed them to fit with a Exacto knife. The small flexible cable must be folded around the inside edge of the plastic frame and then folded again to meet the connector. Follow the folds of the original cable.
On reassembly I used a very tiny bit of double sided tape on each of the side rails, near the screw holes to hold them in place while putting on the outer most screen backing shown in step 6. When replacing this part pay special attention to the two small tabs at the bottom which must slide into slots at the bottom of the screen assembly.
