1975 duster K member

You can actually use any K from 68-75........72 and earlier, you will have to use the old style "pillow" mounts, and 73/ later you will use the "spool" mounts. Everything else will bolt right up.
Not if he's got the late anti-sway bar- it goes through the K frame instead of around it like on the '67-'72 Ks.
