You'll need to pull it apart to at least the upper jacket. The rack and the sector are directly across the column from the key.
I'm guessing you already have Jim Shea's papers?

The long slender pin on the top of the column is what locks into the lock plate. If the sector spring is disconnected it may not lock. OR as Tim stated the sector gear may not be synced with the rack.
I've got some great articles from the web. If you need them shoot me a PM with your email. Also I just went through my column so it's kind of fresh in my mind.

Personally, I would remove the lock pin and spring. has something to do with turning off the engine in an emergency situation and also having the column lock so the car can't be steered. Either way, Streetrat, could you also send me the documents. I just got and extra column to play with in anticipation of doing the Borgensen retrofit. My email is mg8t7gn@aol.com. Thanks.

The pin only comes out in the lock position. If you turn the key one click back to shut off the engine the pin does not come out and the car can be steered to a stop.

I'll take your word for it. I haven't had the need to experience it yet. In my case, I haven't had the shift to reverse to remove the key linkage in my car for over 40 years.

What year C3?
Jonsz06,
You never mentioned what year C3 that you own also if you have a standard (non-adjustable) steering column or a Tilt & Telescoping type.
There was a Z07 Off Road Suspension and Brake Package available from 1973 through 1975 but there was never a Z06 option available for any C3. So your Corvette Forum name doesn't help.
The type of steering column is important because the head portion of the standard column versus the T&T type is very different.
All GM vehicles with locking steering columns had lock cylinders that had the following five positions: START, RUN, OFF, OFF-LOCK, and ACCESSORY.
Also, the 1969 through 1976 C3 steering columns had a lever on the lower end of the steering column (out in the engine compartment) that attached to a cable coming from the vehicle transmission. You had to be in PARK (auto trans) or in REVERSE (manual trans) in order to rotate your ignition lock cylinder and key from OFF to OFF-LOCK.
The 1977 model year there was a basic steering column change that affected all 1977 through 1982 Vettes. The cable was eliminated and a small lever was added to the steering column head, right behind the ignition key and lock cylinder. You had to trip the lever with your finger in order to be able to rotate the lock cylinder from OFF to OFF-LOCK.
Supply some more information and possibly I can help.
