I needed to replace the bezel under the glass on my ipad 2. Of course iFixit had exactly the part I needed and all the requisite instructions as well. You guys are marvelous!
Since I was the one who repaired the broken glass before, taking it off again and replacing the bezel was no problem.
Use a heat gun, not a hair dryer, and watch out for those WiFi antennae.
