Barstow Configurations from the Movie "Bullitt" 1.2

This version corrects the issue with the rear suspension that arose with the recent 0.5.3.0 update. It replaces the leaf spring suspension on the "Mustang" with 4-link and removes the now troublesome components of the rear leaf spring suspension on the "Charger". While this is less accurate than the previous version at least the wheels won't break off immediately anymore. This version also removes the lettering from the hood making these look closer to the movie cars.
