Making progress- - - - -initial measurements on both torque tube/driveshaft setups look like the project is doable without commissioning anything really exotic beyond what an average-capability machinist can accomplish. The adapter will clamp onto the Saginaw rear housing with 3 setscrews.

Edit: I believe a similar adapter could be fabricated to marry up a T-5 with a torque tube. The length of the torque tube and the internal driveshaft would probably have to be altered to match the length of the T-5 box. That wouldn't be a particularly difficult procedure, just involving some basic machining and welding.
