I'd think your better bet would be to dig around and try to find the owner. I mean, tehre can't be too many of these out there, right?
I'd think that between all the Yota boards, somebody would know who made this thing.
Then we overburden the guy with 4 million questions!

In all honesty, just "making it go" shouldn't be all that complicated. People do thsi w/ FWD cars all the time... you only need the front half to drive at all, just cut it off and attach 2 together.
My bet is, they just removed the rear driveshaft, and each half runs on the fronts w/ hubs locked. Put the "rear" t/c in neutral (or unock hubs), and off you go.
