becouse A-Bodies have less then ZERO room in the engine bays. TTi has a PDF you can read for there recomended mods for column
shift cars. they also explain briefly about 73-up suspensions.
cheers
as far as i know, the front suspension is virtually identical from 67-76 on A-Bodies. the exception being the 67 only pitman arm, the 73-up disc brake with
the larger balljoints, and some 6cylinder cars used a straight centerlink up to 1970 or so.
