Are they thr holes underneith the over hang directly above the gauge bezel? If so, they should be there for trim
There is no bright trim, other than the chrome ring that is installed on the gauge cluster, of a 69 Road Runner.
Plymouth B bodies that have a plastic face over the steel dash ... Satellite , Sport Satellite and GTX have a piece of trim that goes all the way across the top of the dash , this piece is not on a Road runner or a Belvedere.
