Drag Coefficient Question

[71GSSDemon]

Does anyone know the Drag Coefficient improvement that Dodge found between the standard 1969 Charger and the Charger 500?  I found that the unmodified Charge was 0.484 while the Daytona was 0.28.  I can not find the improvement of just the flush grill and fast back rear glass.

15% improvement over the standard Charger body according to Chrysler. So....   .411

Thank you!  Still horrible then.
