true to a point, but if you are going big block, and disc, your going to have to change the hole stearing system. reguardless if it is new or not. need a 73 and up centger link, 73 idler and pitman arm. don't need to change those if you are doing SB

no thats not 100% true. all you have to change is from the lower balljoint to the upper control arm. meaning you need the 73 upper control arm,spindle/rotor/caliper, and lower ball joint. the 73 centerlink, idler arm & pitman arm is not needed for a small block or a big block. the 67-72 have a drop down V-8 centerlink that fits a big block c-body pan in an A-body perfect. but yes the bushings and ball joint have to changed no matter what motor you put in if your going to a 73 disc brake set up.
