Who's Created/ Converted a Short 727 Using a Truck Tailhousing to a Slip Yoke?

OK, found it, & when I acquired that thing 30+yrs. ago it appeared shorter for some reason. I had decided not to use it, after getting the parts to build it & a Transgo kit, it stayed parked in a tote & boxes ever since.
To stay on topic, a custom shaft, & TIG welding the extension housing with a section taken out may be it. There appears to be enough meat on the shaft to shorten & re-spline it with about 7.5 inches cut off, but it would need re-hardened,......not sure what the effort/cost/durability delta is on that end........
