engine assembly question, oil pan

I have my 440 all painted up and ready to be dropped into my 71 challenger, but I hit a snag. Now that I am getting older, my memory has slipped me. What is the order that the oil pan, gasket, and windage tray go on? From the engine does it go windage tray, gasket, oil pan? Or does it go gasket, windage tray, oil pan? Any help?
