54. Not at all difficult, just a PITA. First remove the steering wheel with a puller. Next, remove the lock plate with the proper tool. Next remove the signal light switch. You won't have to pull the switch all the way out. There is enough wire on it to pull it up and over the steering shaft. Next look for a screw that looks like it goes into the ign lock cylinder. The screw may be a torx head or phillips. Remove the screw and leave the lock in the locked position. Pull it straight out. now remove the key from the new cylinder and slide it in keeping the cylinder lined up with the locked position. The cylinder will stop once bottomed out. Now put the screw back in, test it. and reassemble all the rest of the stuff you took out. jim

You CANNOT leave the tumbler cylinder in the Lock position to remove it. The key must be in the cylinder and in the "RUN" position to be able to pull the cylinder out. It is a theft deterrent.

All of the 73-78ish columns I have faced have the spring button holding the cylinder in. However, I do know '82 and up columns use a screw that holds the cylinder in.

Josh, you are right. I assumed his was a later year. I didn't look at his signature area, my mistake. In addition, when they cast the shift bowl, they leave a thin aluminum plug over the access to the plunger and this plug has to be broken away before you can reach the plunger. Sorry for the wrong info. Jim

Also if you dont have the tool to compress the lock under the steering wheel its easy to make one out of a piece of metal and you lock it in place with the steering wheel nut and use a couple of bolts and nuts to compress the plate in there....you qill also need a drill to make holes in the piece of metal youre using as a tool that you have.. thats how i got one off once

you need a steering wheel puller and also the spring compressor BOTH can be rented for 40bucks at autozone and when your done and take them back they give your 40bucks back
put the key in the ignition
1.remove horn button pops off
2.remove 3 philips head screws
3.remove 21mm nut im not 100% on the size
4.use the steering wheel remover and put screw the 2bolts into the steering wheel turn the middle 3rd bolt till the steering wheel pops off
5.push the locking plate down with the compresion tool and theres a small ring you pull off then the plate will release
6.remove the 2 then metal strips on the right hand side attatched to the white plastic piece(blinker switch"
7. remove the blinker handle and pull the white plastic piece out might be 2 screws cant remember
8. remove a small bolt or philips head screw on the right hand side about a half inch down the tumbler
9. move the key around till you can pull it out

sounds lot alot of stuff but once youve done it if you ever need to do it again it sould take lik 15minutes

alrite i got it done mine didnt have a screw had to tap on the little slot and pulled it out, but that wasnt the problem so i just did it for fun basically hahaha, i think the ignition switch itself or the rod is messed up for now i wired a toggle switch up 2 the starter to bump it over works fine.

thats what i have kind works as a theft thing also but anywho if your ignition switch is bolted to the top of the colum you should be able to loosen the bolts and slide it back and forth till its adjusted properly

well the truck left me stranded again last night. no power would come on at all but with the toggle it still cranked over so i drop the collum and took off the ignition switch then i went to just to tug on the rod and the whole thing came out it was disconected and bent to hell. now i have to figure out where i can get one at and how to replace it.

And here's a link to a thread of mine with the location of the hole that needs to be broken or drilled in the thin metal of the steering column base with pics.
