The standard horizontal bar grille was physically the same from 1970-72 in all Valiants, Scamps and Dusters. Some had black center sections while the outer sections were argent. Others had the argent in the center with black painted outer sections. The Duster 340/Twister grille, also known as the "Egg crate" or "Shark Tooth" grille, was available in argent only during the years 1971-72. The "Cheese Grater" grille was the nickname given to the grille in the 1971 Plymouth Barracuda. The 1969 Valiant grille is not factory correct but will physically fit in the opening. The parking lamp wiring may need modification to connect to your existing wire plugs.
