Extrapolating this idea further, we end up with the gearbox affixed directly
to rear of the engine block...... May as well utilise the 105/115 design
and save the heartache.
Looking through my engineering submission notes I see that the Alfetta
wheelbase is 2400mm (sedan I believe). My design came in at 2200mm, noting
that the engine was fully positioned aft of the front axle line. In the
Alfetta the engine sits substantially forward.
By moving the relative engine mass rearward one would end up close to 50/50
distribution, even using the 105 driveline design. Moving the driver seat
aft would help in fine tuning.
As a spaceframe clubman design using Alfa components would weigh less than
800kgs, the performance and handling should be adequate for most tastes,
even in the absence of perfect 50/50 WD.

If you're building a car from scratch that will have a shortened drive
shaft, why use the Alfetta drive shaft and Guibos AT ALL? I'd fabricate a
torque-tube (which Alfa SHOULD have done with the Alfetta design in the
first place) and dispense with the troublesome guibos. This simplifies
everything. The engine and transaxel move together as a unit (rather than
independently) and no U-joint is required. This means that the shaft can
be one piece, significantly lightened, and balanced only once, and that's
just before assembly. The heavy drive- line is what I blame for the
Alftetta line's poor throttle response when the clutch is is disengaged
or the tranny is in neutral.
