These measurements can be sent to a hardware or home center store to have an item cut from stock glass to the right size. You can cut the glass yourself if you possess the appropriate tools.

After installing the new pane, run a small bead of caulking along the edge to ensure it is weatherproof. Install a glazier's point on both sides of the frame. This will secure the pane. The points shouldn't be so tight as to cause friction between the frame and sash however they shouldn't be too loose.

Before applying the putty on the surface, knead thoroughly until it becomes soft and free from lumps. Then, roll it into pencil-size strips. Apply the first strip to the corner of the frame. Work from one corner to another to ensure it's even and smooth.
