The mirror attaches at only one point in the center (ball and socket type fitting) and likely has two wires that crimp on to allow the heated mirror. My memory is the plastic backing just pries off from either side once you have rotated it to allow pry space and used some thick rag to cover the shell so you don't mar the paint. Your luck is not all bad as you don't have to worry about cracking the glass in the mirror any more. It has been probably 11 years since I did one. You do have the option of installing a special Aspheric mirror which allows you to better cover your blind spot at the cost of some slight distortion. I liked mine on my first Boxster so much I bought one for my second and if a newbie like me could install it...
