Preheat oven to 350 degrees.
Beat eggs and egg whites at medium speed of a mixer until well blended. Gradually add juice, rind, and milk to egg mixture, beating until well blended. Spoon mixture into crust and bake at 350 degrees for 20 minutes or until almost set (the center will not be firm but will set up as it chills.) Cool pie on wire rack. Cover loosely, and chill 4 hours. Spread whipped topping evenly over filling.
