Is it possible to:

install the rear window glass backwards?
I have tremendous and annoying reflections in my rear view mirror. A new windshield, mirror and rear window tint has not helped. When I look in the mirror I see refections of everything in front of me. The dash, hood, road and any car that's in front of me.
Tonight, I was looking at the rear glass and noticed the label (or whatever you call it) that shows it's "Softray" glass, so I assume it may be original GM.
Sooo, it looks like the glass is flat? Is it possible to install the glass backwards and maybe this has something to do with the glare on the inside? The label is on the passenger side, lower corner and is readable from the inside. If the glass was reversed it would be on the driver's side and readable from the outside which makes more sense to me.
