There is some bolts in the dash and some on the fire wall. Take them out. The best way I have found to get the coloum off the pot cupling is to take the pin out. There is a pin going into the cupling. Take a scruedriver and work it out. That should get it. Not hard at all.
There is two pins one that holds the pot cupling on the steer gear (big one) and a smaller one that holds the guts in to the pot cupling. I take out the small one my self. but ether one will do it. If you take out the small one. Don't loos the guts.
Good luck.
