Glazing bead/spine

I need to replace the Glazing bead/spine on a Wenco JX-7 double hung window. window glass is double pane 28 7/16 x 28 7/16 and about 1/2 thick. this was one solid piece. I cut in half for you to see. both sides should look identical but you will see in the pictures that one side is damaged and missing the bead that extends out from the edge of the sash.
