I'll go ahead and say that that data tag has been swapped to that glovebox door. That is a '74-'77 Dash, so it could have had a dash swap. Or, it could be titled under a different VIN.
As far as Explorer Colors, there were several besides blue and copper. And yes, there has been a black '73 Explorer on this site with orange interior years ago.
Standard Explorer Colors:
Durango Tan
Hot Ginger Metallic
Grabber Blue
Burnt Orange
Viking Red
Brook Blue Metallic
Copper
Blue Metallic
On top of those, I've seen several others that were not standard color, but still had Explorer package. My Dad has a Hatteras Green '76 Explorer.
