They are both about 1-1/16 from the the start of the splines to the runout of the taper, so the steering wheel will sit about the same on both shafts. The old shaft has a wider relief between splines & taper start.
The old shaft, with spring and lower clamp, could be extended more from the top of the column creating more clearance between collar and wheel.
The new shaft location is fixed by snap ring on shaft.
