Hi,

I talked to my acquaintance.  He suggested checking with a local custom
glass store what they would feel comfortable with in terms of oversize
and then aquire the mirror from edmunds.  His assessment is that the
risk of damage is low as such houses cut mirrors all the time and a good
hard finished front mirror is not easily dammaged.

Considering the application, he feels Edmunds quality is fine.

Regards,
John
