I'm looking at buying a 78 NYB St. Regis and I have a few questions: 1. Anyone know the production number for the St Regis package? 2. The fender tag has a N02 code in the upper right corner. What does that code mean? 3. Does the 440-4 (E85) engine have a catalytic converter? This car is largely unmolested other than a color change. It even has a functioning lean burn system!
