Here is a quote from musclecar.com about the 1967 Impala.
"The Impala also had a host of new safety and convenience features, including a dual master cylinder brake system, an energy absorbing steering column, and an ignition switch illuminated by the first use of fiber optics technology to appear in a Chevrolet."
I should not have included 67-70 pickups in my previous post. My 71 Chev and my son's 71 GMC have fiber optic lit gear selector on the steering column. Not sure when it started.
