the guys at the shop dont understand what im needing
What guys at what shop?
Where do find these inept people?
Your window is no different than a lot of windows. The frame is sized for the metal frame and double pane you removed so that's what has to go back in. ANY reputable glass shop will be familiar with your needs. Take them the old frame if they need a "Windows-101" illustration.
Are you sure there was "putty" holding that glazing in place?
