The possibilities of dates on those 2 carbs would have been early, right on, late, or built several years after 1971. All means nothing because they never put a 6125 AVS on a RR. But there were C-body 383 4 bbl cars built the same day your car was and the carb date would be right.
You see how it all goes full circle?
Nay nay. If built several years after, it definitely would have meant something.
