Are you sure it is the original gearcase??  Early models used pinion that was keyed to the driveshaft, later models used a pinion that was splined to the driveshaft.  Your 1958 came with a keyed pinion, but perhaps the gearcase was changed using the splined pinion.  These two driveshafts are slightly different in length.
