Re: Ignition switch cylinder removal

Here's what the '78 shop manual has to say about it. Let me know if you need more.

(1) Insert key in lock cylinder and turn cylinder to Off-Unlock position.
(2) Disconnect battery negative cable.
(3) Disconnect harness connectors at switch.
(4) Remove switch attaching screws.
(5) Disengage remote rod from switch slider and remove switch from column.
(1) Move switch slider to Accessory position (fig. 2J63).
(2) Move switch slider back two clicks to Off-Unlock position (fig. 2J-63).
(3) Engage remote rod in switch slider and position switch on column. Do not move slider when positioning switch on column jacket.
(4) Install and tighten switch attaching screws to 35 inch-pounds torque.
(5) Connect harness connectors to switch.
(6) Connect battery negative cable.
The key-operated lock cylinder is located at the upper end of the steering column and is mounted in the column housing or cover. The lock cylinder is a two-piece assembly and can be removed, disassembled, and repaired or recoded if necessary.
Lock Cylinder Removal
(1) Disconnect battery negative cable.
(2) Apply protective material to painted areas of column.
(3) Remove steering wheel.
(4) Remove lock plate cover. Use two screwdrivers to pry cover out of column.
(5) Compress lock plate and unseat steering shaft snap ring as follows:
(a) Inspect and identify steering shaft nut thread-type. Metric shafts have identifying groove in steering wheel locating splines (fig. 2J-2). American thread shafts do not have this groove.
(b) If shaft has American threads, use Compressor Tool J-23653 as is to compress lock plate and unseat snap ring (fig. 2J-5).
(c) If shaft has metric threads, replace compressor tool standard forcing screw with Metric Forcing Screw J-23653-4 before installing tool on steering shaft.
WARNING: The lock plate is under strong spring pressure. Do not attempt to remove the steering shaft snap ring without using the compressor tool.
(6) Remove compressor tool and snap ring. Discard snap ring.
(7) Remove lock plate, canceling cam, and upper bearing preload spring.
(8) Remove turn signal lever attaching screw and remove lever.
(9) Press hazard warning knob inward and turn knob counterclockwise to remove it.
(10) Disconnect turn signal and Cruise Command wire harness connectors at base of column.
(11) Remove turn signal switch attaching screws and move switch aside to provide working clearance. It is not necessary to remove switch and harness completely.
(12) Insert key in lock cylinder. On manual transmission columns, place cylinder in On position. On automatic transmission columns, place cylinder in Off-Lock position.
(13) Compress lock cylinder retaining tab using thin blade screwdriver and remove lock cylinder from column.
NOTE: The lock cylinder retaining tab is accessible through the slot adjacent to the turn signal switch mounting boss (fig. 2J-8). If the tab is not visible through the slot, scrape or knock any casting flash out of the slot to provide access.

I might have been born at night, but it wasn't LAST night.

Heck, the cylinder falls out of my 94 YJ every time I'm in a hurry and don't get the key in just the right position before I pull out the key!
