I had a brain fart. 
What I meant to say was to have a TII driveshaft made. I could use a stock shaft, but they have weak and non-replaceable u-joints. The local driveline shop can make me a brand new TII sized shaft that has massive u-joints (they come from some kind of huge Dodge truck) that are easily replaceable. So that's the direction I will go. My TII trans to NA diff shaft (with big u-joints) will be up for sale at some point ($200 is the price).

Once I get some space for metalworking that'll change.
I usually like an off the shelf part unless there's a good reason to fabricate.
Ability to replace universal joints sounds like a good reason.
If you read, you'll note that he blew the N/A trans and put in a Turbo2 unit.

Personally I'd love to be able to make driveshafts and axle shafts myself, but I lack the necessary balancing equipment. However the local driveline shop is friendly and inexpensive, and do good work. I can have them make up almost anything as long as I am clear about the spline patterns, flanges and length.

In that most driveline places dont have the ability to balance a shaft at the speeds racecars see. Thus he was getting high speed vibrations (80-120+ mph). Now we buy them from the driveshaft shop. As they have the equipment to do the high speed balancing most places don't. I think that all the mazdatrix driveshafts are built by those guys (but dont quote me).

The words you are looking for are "DANA" and "SPICER". And yeah, they are so much better than the stock joints....not even close.

with an overdrive in the trans the driveshaft rpm can be over 10,000...

The local driveline shop services most of the race teams in the area, so they don't have any issues. I've had shafts made by them since 1999 and have never had a balance issue.
They LOVE our RX-7s. Everytime they hear the "brap brap brap" all work stops and they are in the parking lot.
