Will a 1995 or 1996 Camaro steering wheel fit 1999 Camaro?

No, a 1995 or 1996 Camaro steering wheel will not directly fit a 1999 Camaro. The steering wheel and column designs changed between the fourth generation (1993-1997) and the fifth generation (1998-2002) Camaros. The splines (the interlocking teeth on the steering shaft) are different, preventing them from being interchangeable.
