Link to the roadrunnernest showing paint colors for louvers (all other colors got flat black louvers).

Agree with others, V21 indicated the hood blackout behind the AG bubble (although I've seen a few cars not coded V21 that did have the paint blackout).

The rear bumper/valance blackout was part of the A87 package on road runners and separately coded M75 on GTXs
