Is a camaro and firebird close enough to interchange the steering column?

No, Camaro and Firebird steering columns are generally not interchangeable, even between similar model years. While they share a platform and some parts, there are enough differences in the design and mounting points to make direct swapping difficult, if not impossible. You might find some very minor parts that *could* be swapped, but a complete steering column is unlikely to be compatible without significant modification.
