A mirror/glass place is probably your best bet if you want to save money and
get the right size, and don't mind re-using the old mirror mount. In a pinch
on a trip I went even cheaper and just cut the glass out of an old non-power
mirror I had under the seat and stuck that on the broken mirror with 3M
weatherstrip adhesive (nasty rubber/contact cement stuff, smells like model
glue). Red permatex would probably do a fine job as well. The glass is about
1-2mm smaller than the original all around, with slightly curved sides and
larger radiused corners, but it works. Probably one of the better "baling
wire" class repairs I've made.
