The non-stock R-model valence that I’m running has a large opening to direct additional airflow but there is nothing to protect the radiator from debris - I made a screen out of wire mesh and attached it directly to the radiator support. My car is a 68 but I used the grill from a 67 as it has fewer tabs for badges and trim. I removed all of the remaining tabs for a clean look. I also blacked out the aluminium radiator with a light coat of high-heat paint.
