Why a 2 piece driveshaft?

Yep - the '73/'74 SWB 454 trucks had a two piece shaft. There's so many more variables than just wheelbase.

In the GMT400 and GMT800 versions we started using "exotic" materials like aluminum and carbon fibre wraps in larger diameter shafts - all with the motivation of taking some of those two piece applications and turning them into one piece (saving the additional center bearing hardware and complexity).

Believe me, the engineers wanted one piece shafts wherever they could get away with it, too.
