need help 68 dart ip/ instrument cluster removal

If the car is column shift, set the park brake and pull the shifter down to neutral. Remove 3 fasteners at the top of the steering coulmn and let it drop. Cover the column with a shop towel to prevent scaring the paint. Remove one screw from the fuse box. Lift the fuse box up about an inch and set it back about an inch. It should hold itself against the back of its hanger. Next pull the headlight switch to full on. Reach in at the right side of the switch and push the small release button so the stem can be pulled all the way out. Remove the bezel nut from the switch and leave it lay in the dash. Remove all the screws holding the panel in the dash.
Grab the speedo cable sheathe near the firewall and pull/push toward the instrument panel. You should find enough length in that cable to push the instrument panel part way out of the dash.
now you can disconnect the speedo cable and other connectors through the openings you've created.
I know all this isn't in correct order and it isn't how the factroy service manual says to do it but if you've done as many as I have with a bad back too...
I can't lay upside down in the drivers seat. I can drop down on one knee at the drivers door opening and reach in.
I leave both light switch and wiper switch in the dash rather than feck with their harness connectors Good luck
