Kick down 904 bell crank for 1966 273

In '66, the 2bbl lever on the bell crank is straight and offsets to the inside (toward the carb). The 4bbl one is curved and offsets outward toward the fender because the AFB is wider than the BBD. The bell crank to carb rod and connector is carb specific too, but, the rest of the kickdown linkage is the same.
