What year is your Charger ?? . . . I put a tuff wheel onto the column of my 1980 M body (non tilt) . . . only issue I had, was that the hole where the wire for the horn comes thru on the adapter, I had to open up a little bit to fit over the piece on the 1980 column. Sorry it was the hole opposite where the wire is for the horn. I believe all adapters have the master spline . . .
