Combine the sugar, salt, and spices in a small bowl.
Beat eggs gently in large bowl.
Stir in the pumpkin. Stir in the sugar-spice mixture, then the vanilla, and then the butter.
Gradually stir in the evaporated milk and mix thoroughly.
Pour the pie mix into the baked pie shell, and tap gently on the counter to remove any bubbles.
Bake for 60 to 70 minutes or until knife inserted near center comes out clean.
Cool on wire rack for 2-3 hours and then refrigerate for at least 4 hours. (Do not freeze as this will cause the crust to separate from the filling.)
