I have always preferred the 1967 and 1968 Firebird front grille/headlight/chrome trim look over the 1969 look. But, I always liked the "lower/sleeker" sheet metal look of the 1969 Firebird. Would it be a major job to put a 1967 or 1968 "front" onto a 1969 car, or would it be relatively easy? Thank you.
