| Steve,
I had the same problem on the SS with ater damage, stick them in the oven (dunno at what gas mark!) at about 80C and the adhesive softens enough just to be able to pull the glass away from the mirror without damaging the surround (or paint) and then stick the new ones in with some adhesive from a car bodywork place (for sticking trim on) called stay tack or something......
