Does a 1991 Chevy Camaro steering column fit in 1992 Camaro?

No, the steering columns from 1991 and 1992 Camaros are not interchangeable. There are significant differences between the steering columns of the two model years, particularly with regard to the ignition system. The 1992 Camaro was the first model year for the car's third-generation, which brought with it a number of new features, including an integrated theft-deterrent system that involved the ignition switch and the transmission shift interlock. This system was not present in the 1991 Camaro, and therefore the 1992 steering column is not compatible with the older car.
