Are the wheels big bolt pattern? Meaning 5 x 4.5"?
If I'm not mistaken the 73+ K members have spool mounts and the lower control arms allow for a narrower sway bar that runs inside of the K frame. Meaning the sway bar is mounted inboard a few inches. While you are at it get the 73+ upper control arms and disc brakes it's a bolt on swap. Hope this helps.
