'72 Trans Am Ignition Switch?

[njsteve]

If you dont have the backdrive linkage that connects to the reverse lever on the trans hooked up, the collar wont spin and you can accidentaly bump it out of sync. Grab the lower portion of your stearing column and rotate it left or right. As it goes to the full turn position you should be able to get the key out. This system, when working properly ensures that the car is placed in reverse (on four speed cars) before you can remove the key. It also activates the column mounted switch for the backup lights.
