Nissan GT-R transaxle driveshaft

Paul Frère in the May 2008 Road&Track on the Nissan GT-R:
Surprisingly, there is no rigid link between the front engine and the aft transaxle, the latter located forward of the rear-wheel centerline to reduce the car’s polar moment. A carbon-fiber propeller shaft takes torque to the transaxle; another prop shaft brings allotted torque forward to an open front differential. [NB: It's a 4 wheel drive car]
1) Frère clearly doesn't know Alfas which had this 25 years ago (circa 1972).
2) More to the point, how does Nissan do it? Are there guibos or universals? Is the chassis so rigid it doesn't need them?
3) Some people have made carbon fiber driveshafts for transaxle Alfas. Do they use a center guibo?
Inquiring minds want to know!
