Disassemble a sport mirror

I have done the same thing as Oldmanmopar, and it works well. Don't do it to a painted mirror you don't want to ruin, but on a chrome mirror like the one you have....soak it in lacquer thinner to get the adhesive on the mirror glass to turn loose. You still have to be careful taking the glass out, but it is a LOT easier to get out after soaking it.
