Will a Radio from a 1996-1999 Riviera fit and install in a 1993 Riviera?

I would have to say yes. I checked to see what wiring harness adapter fits if you were to install an aftermarket stereo and it fits from 85 up. So the only thing I would double check is that plug is the same. If the plug is the same and the stereo is the same size then no problems. Here is a pic of the plug.
