1974 J-10 ignition switch removal / replacement

[Tigger4X]

Long story short the key has been broken in the ignition of my '74 J-10, non-tilt. Being an OTR driver family would move it for me to avoid city code enforcement issues re: street parking. I came home to a broken cylinder switch so now I have to replace it. I used the Search, but wasn't finding much and what I did find hadn't panned out. A number of the search results had pics once upon a time, but Photobucket has turned into Photo and you cant see them any more.

I googled some and came across a YouTube video, link below. I had read in one of the aforementioned search results that on many untouched columns there was some casting flash over the holes mentioned in the video so I knocked them open. I tried wiggling a narrow straight blade as was mentioned in the video, but the ignition switch won't budge. I haven't been able to locate the locking rod mentioned though.

Does anybody have any pics that can shed some light on this? TIA

Did you pic up a new switch yet?
The tube vid is effectively dead on although it looks a bit different in my column. I had it open and changed mine a few months ago. Basically when you get the screwdriver on the push down tab...it comes out. I have another cylinder at the shop, I will look at it tomorrow.

Well, I guess it links it but doesn't show it.. anyway not sure if it helps but I am pointing to the tab which is depressed straight in.

Yes, I have the key cylinder switch in hand; ordered it from BJs Off Road. I've watched the video a number of times and gone back and forth between it and the TSM, jeep threads, etc. Doing so helped me discover the casting flash as I mentioned above. I've tried the screw driver wiggle as the video suggested and it didn't yield results. I have yet to find/figure out where the locking/connecting rod mentioned in the TSM, etc is and how to disconnect it. Although I don't see where this rod or anything else connects to the ignition cylinder.

The video did suggest using a thin straight blade and thats what I used. I'm looking for a thin, sturdy piece of metal hoping it's a matter of depth that is the problem releasing the retaining tab.

normally a functional key eases removal IIRC.
kinda poor man?s anti theft
IIRC and I could be wrong? key needs to be in with cylinder in off position

A glimmer of light at the end of the tunnel. Nope. Its a train.

A functioning key would be nice; mine was broken off in the cylinder.

There is a nub on the bottom side of the cylinder that clears once the key is in the run/start position. Once that is out of the way the tab on the front/facing you can be pushed in and the cylinder should then pull out.

That is should. The nub was broken and jammed in there somewhere and was holding up the cylinder. That and a long thin rectangular plastic tube that has two contacts on it facing you. There is a long thin slightly curved metal piece that seemed to hold it in place. Well that lil bugger sprung back and into the colum. With it and the plastic tube out and fighting the broken off nub the key cylinder is out of the column. Next up is pulling the column to find where that friggin slightly curved metal piece went.

I just remember fighting w/one, after jamming a key(not correct one) it came right out. I never got keys when bought it. Wanted to see if it would start/run.
If key is busted off inside, may need to fight with it??
Like taking a small chisel or dremel to that tab that won?t depress?

Also always the car thief way, drill it out.

The ignition cylinder is out. That nub was one of the things hanging it up. The new adventure is how to get the thin slightly curved metal piece out of the column from wherever it went when it recoiled into the depths of the column.
