It's a very rare option that I've been looking for. I've contacted every "antique parts" supplier I can find and NONE of them offer anything for these windows. The only thing I've found is 2 pieces of NOS glass - $250 ea!!! If you decide to change to the normal glass, I'd be interested in the sliding ones, no matter what the condition.

BTW What's wrong with them?
