[halfstep]

Throwing my 2 cents in because people here love to solve these mysteries and of course so many are skeptical about the "realness" of Cheyenne's and Supers...

Unlike non Supers which had visibly painted glove box faces, my guess is it could just be to save the effort of painting or was forgotten and not worth the effort to fix since when closed it would be covered by the woodgrain. The Super glove box doors I've seen had a thin aluminum cover skin which the woodgrain was applied to. If everything else checks out, I'd say they grabbed a black door stuck the aluminum/wood grain skin on and slapped the SPID on it....consistent with what Joe's Junk said.
