Big Block Steering Mods
It's hard to tell but it looks like you turned/cut the shaft down so much that it was too thin to handle the torque. It also looks like there's a "floating" rod/shaft inside the steering shaft otherwise the two pieces would separate when you turn the shaft??
Many companies make straight steering shaft couplers. I would cut the original shaft off (where it is too small) and attach one of these couplers. Like I said before I prefer the "split/pinch" type couplers because they won't fail even if the bolt comes loose because the bolt goes through a slot/groove in the shaft. That's the way the factory did it on many cars for safety reasons.
Companies (borgeson) also make universal type couplers. Your problem is that too much was removed from the original shaft making it weak. You always want to avoid removing too much from the original shaft. Wish I was there so I could see it for myself and help you???
