I presume the outside piece he wants to remove is adhesively attached to
the glass and wondered if the folks here here can recommend a safe way
of removing it without risking damage to the rear window.

Go to any auto parts store. Look at the mirror mounting kit display.
Many will have adhesive remover as part of the display. Failing that,
try a auto body shop supply store. Again, in the mirror mount products
should have adhesive removal material there. The cyanoacrylate
adhesives are removed with acetone, IIRC. An epoxy adhesive will
soften with methylene chloride, the main component in StripEase and
similar bodied paint removers.
