1971 demon drivers door w/ glass n stuff

Is this item still for sale? I have a 1971 dodge demon with a 440 that used to be my uncles. He recently passed away unexpectedly and he told my grandfather that of he did pass away that he wanted me to have it. I am trying to get it inspected for prom and it means a lot to me. All I need now is a passenger window and regulator and this would be absolutely perfect. Thank you.
