The rest came out in a handful of broken pieces. Most of the nuts and screws hand long since fallen out. For those interested, to the right of the sun glare (sorry about that) there's a screw hole. Attached to that there's a ridge of metal that goes down and to the right. The slot inside that ridge is where you release the key tumbler mechanism.
Here's a picture showing the junk that came out.
The broken piece was the sector gear that turns to move the race and pull the ignition switch. One tiny little plastic tooth broke and shut down the whole project. The hard part was finding a replacement. There are plenty of replacements for non-tilt steering wheels. Those only have 5 teeth. The tilt wheel sector gear has 6. Here you can see the old broken gear and the new black one that came from a Corvette restoration shop. All GM cars with tilt from 69-76 use this gear. You would think they would be more easy to find.
Here's the hole it goes in. A rod goes through that hole and into the key tumbler. That's why these cars were so easy to steal. A thief could pull the key tumbler out with a slide hammer and turn that rod with a pair of pliers and be gone almost as fast as someone with a key.
And here's the column with the gear in place as well as the spring that moves the steering wheel lock post.
After that it was easy to put in the new turn signal switch,
Then the steering wheel lock plate,
and all done. While I had it out, I stripped off the old green and painted it gloss black and the gear indicator red. I've decided to go with a black interior with red accents and red exterior with black stripes.
