You mean "Park was _not_ engaged fully," I assume. Yes, I had the same problem with my old '82 Cutlass. Generally speaking, the console shifter on the floor has a linkage back to the steering column which prevents you from removing the ignition key unless you're in Park, since removing the key also locks the steering column. If you have a column shifter, that'* obvious, but if you have a floor shifter, you might not notice that the outer shift bowl still rotates when you move the console lever. That'* the linkage that enables the floor shifter to control the column lock, backup lights, neutral safety starter interlock, brake pedal shift interlock, etc.
Anyhow, on my Cutlass, the engine had sagged down when the motor mounts rotted out, and that changed the geometry of the linkage at the transmission so the steering column bowl wasn't in synch anymore. Mainly this just screwed up my backup lights, since those are driven off the steering column linkage just like the starter interlock and the steering column lock, but in extreme cases you do find that either you can't crank the starter in Park or Neutral like you're supposed to, or else you can't get the key out, like in your case.
I would get under the car and find where the steering column linkage meets up with the floor shifter cable, probably in the area of the transmission (haven't had to find it on my car yet), and there should be an adjustment for that somewhere to get your steering column linkage back in synch with everything else.
