'73 Duster, no power steering (though it may have prior to the 440). My steering wheel has a fair bit of play in it. Nothing that makes driving it feel squirrelly or anything unsafe, but I'd like to know what I can look at to maybe tighten it up.
You'll need to find where the play is first. Start at where the steering shaft exits the fire wall. Could be anywhere from the box coupling to tie rods or combination of several.
