I believe the part you're looking for your dash is called the HVAC panel. It's P/N is 64118367667 which I found on realoem.com. This piece has little plastic tabs on the back of it which commonly break when the plastic gets old and the panel is removed. I wouldn't recommend buying it used as people will probably try to overcharge you for it and it will probably be broken or break anyway. The panel only cost $17.88 at mileoneparts.com or $22.50 at pelicanparts.com
