I've read other fixes for the scratched glass x-door inners including replacing. After disassembly, the total thickness of the laminated window was 3/8". I was thinking that the outer layer was 3/16" glass and the inner layer was 3/16" plastic, but this was incorrect. There are two glass layers with a very thick plastic "film" on the inside surface that was heavily scratched. That plastic film can be easily peeled off leaving a beautiful window, glass on both sides, that can be reinstalled. Beautiful! (Window must be disassembled to remove film.)
