Can I swap an analog dash for a digital one in a 1990 Cadillac Deville?
 

I am looking to buy a 1990 Cadillac Deville, but the only thing I dislike about it is the analog dash. I currently own a 1989 Cadillac Deville with a digital dash that I would switch for the analog one in the newer car. I have a mechanic willing to help me should it be possible.
