idler arm, center link, pitman arm

You get more but I am not sure how much. With the later set up all the tapers come in from above rather then the tie rods horizontally and idler/pitman from below with the early center link.. I have the '73 up style for my big block conversion but have not set the motor in yet. If you are using a '67 K-frame the idler ARM mount is different than '68 up and you will need to change the K-frame too.
