ok, egg on my face. It is 1974 and prior. but not sure whether the topic starter understands what was right and wrong about my statement. If he is looking at buying a 1974 car, then I gave bad advice. Any other year besides 1974, and my advice is accurate. :) Maybe I blocked those 2 years out of my mind for very good and expensive reasons! WE also came out of that experience erroring very much on the safe side!
