1. Remove the shift rods that connect the transmission arms to the arms on the end of your column. While you are at it also either disconnect the horn wire and/or remove it from the tube entirely.
2. Remove the firewall plate that holds the seal for your column (unscrew from both the engine compartment and the interior). This is a two piece unit.
3. Remove the steering wheel. (some guys like to keep it attached to have something to grip. If you do just be advised that you will be tight on space taking it up to your headliner.)
4. Remove the shift indicator plate from the dash.
5. Remove the turn signal bracket/disconnect the wiring harness.
6. Remove the two machined screws that hold the column bracket to the bottom of the dash.
7. Go back into the engine compartment and loosen up the clamp at the end of the steering column tube (resting on top of the steering gear assembly).
That should be it to get the unit to slide off of the steering gear shaft. Sometimes this little booger can be tight... (referring to the white bushing)
