No it won't! The steering box has a large sector shaft that requires you to use the 73+ pitman arm. This pitman arm mounts down from above into the center link verse the 72 down coming up from the bottom. This would require you to use the 73+ center link and idler arm too.
The problem is the 67 idler arm is a one year only design and the 73+ idler arm will not mount onto the k-member.
The only way to use these parts is to swap in a 68+ k-member and you would need the pitman arm, center link and idler arm as a group.
