OK, try this:
Pry off the cap from the middle of the wheel.
Pay attention to the alignment of the wheel. My car did not have a keyway ensuring the wheel only fits one way on the spline.
Loosen the big nut. You may need an impact wrench. Mine was really tight.
If the nut came all the way off, put it back on with your fingers several turns.
Get a stout puller and hook it up. Tighten the puller. The wheel will likely let go with a bang. That's why you put the nut back on; to stop the wheel flying around.
Take off the nut and remove the wheel along with the "hub".
Take out the 9 screws and little nuts.
Take the trim ring and put it on the wrong side of the hub
Put the steering wheel on the wrong side of the hub.
Screw it all together.
Replace the hub in the car.
You can make a spacer to get the wheel even closer to the dash. This also frees up the trim ring to be put back on the proper side of the hub.
I am in the process of using a spacer to get back most of the space lost by putting in a MotoLita-to-MotoLita easy-off. This only works because the center hole on a Moto-Lita is so big it easily clears the trigger ring on the easy-off. If you try this, be sure you have a way to operate the trigger before test-fitting!
In case I decide to do this the "right" way and weld the male end of the easy-off to the stock shaft, I will need to remove the shaft section, and I have hit an obstruction.
Not your problem, so I will post a help-wanted thread of my own.
