Father-Son 1974 Duster Project

Just stick a pry bar between the front of the couple and the steering box, it slides right off.
Old grease / grime is holding it on.

Also check the lower column bearing on the steering column, most likely it is also bad.
Don't buy the reproduction bearing it is like $80 instead do this mod for $7
