Take the steering wheel off, (big nut under center cover) then there are screws holding the top and bottom steering column casings on, remove these to get the casing off. To get the ign/key lock/ switch out you have to remove (drill out) the anti theft bolts that hold the thing to the column, and then once its on the bench, swap in the cylinder thing (switch body).. If I recall correctly the cylinder is held by bent over tabs or some other flimsy method, you might want to bolster that setup in some way with the new parts when you have it out to save you future issues. replace the antitheft bolts with normal ones, or I guess you could order new antitheft bolts from RN..
not too bad, two three hours maybe..
"Yeah, make sure its a flatbed...."
