Rotation & angle of universal joint?

[Philippe Hurbain]

- Apply like above
- place the connecting axle, make sure it's snapped to the first joint (tmp hide the second one if needed)
- Select the center axle
- rel grid
- select the 2nd uni's first end
- ctrl+home
- rotate 90 deg to align with the axle again.
- reapply the script on the 2nd joint
- snap the steering wheel to the 2nd joint's 2nd end.

Sorry, I don't get it... Problem is that I need to rotate an end joint unit, and I can't figure the needed rotation. The script only places and rotates knuckles and inner joint (next to center axle) units, not the end joint units.
