I just reviewed the Big Block photo record here on board CLICK HERE
I counted 2 1966 Big Block SD's, point being it's a rare beast nowadays. If we don't know of one then I'd say there's a 90% chance that no one in North America does.
You do foreshadow in your last reply that you might already have a line on one however. Is that true?
the one I sold 9 + years ago is still in my name. The guy i sold it to died of cancer not long after. I am thinking his wife has kept the car for one of his sons. I can find nothing of their info that i could call her and ask about the car
