I have seen a couple of 71 Cuda's red with black bill board stripe and top with white interior, but also red with black top with white stripe and interior. I'm pretty sure you could get just about anything you wanted. I do know that a triple black car is hard to find.
Darren I used only the lime green color. After it dried out I washed over it with different green acrylic paint and cleared them with dull cote. I made the stems out of little pieces of railroad Lichen. Hope that helps.
