Beautiful Car.  Question though, why is the "heavy" end of the ujointed half shaft toward the hub instead of the diff.  I know it is mimimal but less unstrung weight.

Fair question. Two notes:

- the outboard end is a large hollow tube, while the inboard end is smaller in diameter and probably solid. For the same torsional strength and stiffness the larger tube will be lighter... so is the heavy end really toward the hub?

Well sir, you are correct.  I am a restoring an old sports/racer with IRS with the  universal jointed half shafts on the shelf.  I weighed the ends on my postal scale with the other end at the same height.  The 'hollow tube" end was several ounces lighter.  Learn something every day.
