I think the steering wheel only fits at one clocking since there is a "wide groove" you must match. It seems I see it in the photos above. However, on the bottom end where the coupler attaches to the steering gear, I looked and looked for a locating groove and found none on either end in my 65 Dart. I know my 65 Newport and 69 Dart had one. Either 65 Darts were different or somebody jammed it on wrong and swaged a new groove. My point is that, you shouldn't booger with the steering wheel or coupler to get the steering wheel centered. You should adjust the tie rod couplers to center it. That is a standard part of alignment. You could mess up the toe-in (bad!) if you try yourself and don't know exactly how to do it.
