How is the factory jack mounted?

I believe that the jack handle actually slides up and into the jack tube at the back end. The rear mount for the jack has a round cut out for the handle. Sorry...no pics. The spring loops into the notch where the bumper mount goes and you then lightly tension the spring using the jack.

The spring doesn't go on the welded loop. lower end of the spring hooks around the tire tool pulling it up against that loop. Upper end of the spring hooks to jack mechanism and a few click with hand will tighten the spring tension.
I don't have a pic. Surely someone does.

I'm interested in changing mine around if I can get a definite answer on which way it goes. Someone must have a pic to share :)

Thanks
