Spirit of 76 duster ... is there a Code ?

Nobody ever answered his question. Now it is 12 years later and I have an answer for you. They did not make a Spirit of 76 Duster package. It was only in the Dodge Dart and on the Dodge pickup. On all the Dodge Dart Spirit of 76 cars that I have seen or people have sent me pictures of their Fender tag there is a Y39 code. This means special order.
And they did make some with the 360 in it. Mine is originally a 318 air conditioning car.
