Okay, to solve this mystery...
I've been driving around with an upside-down steering wheel for a while now, and then started working on installing some side view mirrors, finally returned to this.
Since everyone was scratching their heads (including me) on this one, I decided to try ONE LAST TIME. So I pulled the crush can off, looked at the keying, aligned it, rotated 180 degrees, and started bashing it.
Net result: it went on and the steering wheel is right side up.
Now I'm scratching my head at why it worked both ways when its supposed to be keyed... The level of effort to install it was roughly the same both ways. I did note that the metal coil that is responsible for turn signal return was positioned properly after the 180 degree turn...
