67-69 cuda door glass

thanks guys. I figure that the coupe/fastback had the same glass. I knew conv was different, yet the FSM has same part # for all 3 models. ?? Maybe I read it wrong. either way, I was selling a piece of glass to a guy and it was curved. I have the door as well and I was 99% sure it was from a fastback. I got a pair in trade, so I never took them off the car.
