Well, that is probably a Carter carb and it will be taller and not have all the linkages in the same places.
You are probably stuck with a 1979-1982 (even those were different carbs!) style carb, so the linkages all fit and work. I have been looking for another 1982 carb to try some different turbo mods to. (I have the 1982 year Holley model 1946 carb on now)
