    i would say it would bolt in, but it might be a little narrow.you might be able to use it with a different backspaced wheel but im not 100% sure on it. hopefully someone who has one of the 73-75 body styles will chime in.

    I'm gonna disagree. 68-72 A-bodies used different lower control arm brackets and the spring seat is in a different location vs. 73-77 A-bodies. Even the sway bar mount differently for either vintage.
    68-72 A body rear end
    73-77 A-body rear end
