ITs glue, you can do it, but not with force as the glass will crack, dont ask how I know. Go on to the Google to get more info of how to do it, youll get it off, clean the glue and reglue it. THe windshield guys do it all the time to swap your mirror into the new windshield. Go and ask one of them, not over the phone; face to face gets better help, shows your a real person and all the psych stuff.
