Excessive play in steering wheel ?

Good explanation Rob, I see he is new here and may be new to 60s mopars
also. The front suspension may be completely rebuilt and it may feel loose to him
compared to a more modern car he is used to driving with rack and pinion steering.
Being new you do need to do a bit of getting familiar with the suspension parts. What they are called and what they do.
To put it simply you will need to be looking, feeling and listening at all the movable joints for slop or lash that create a delay in tire wheel movement to steering wheel input. Have someone
help you shake it down.
My experience has been when I pick up a old mopar previous owners seem to neglect
the lower control arm bushing more so than all the other parts. It is the hardest suspension wear part to replace and gets skipped often.
Have fun and be safe.
