Cars look great Jeff, fwiw, 1967-68 F-body's (Camaro/Firebird) had round wheel well openings, '69 had squared off openings. Differences between 67 & 68 get touchy with hide away headlight option and SS/RS packages but dead giveaway is front door "Vent" windows, only 67's had then, so mod is 67 Camaro at this time.
