67-73 are all basically the same. When they went to shock mounted bumpers things changed for the bumper mounts. My '74 has provisions for both the early style bumpers and the late shock mounts (which is how I was able to just bolt on the '71 bumper). Shock mounted front bumpers started in '75, maybe some in late '74. But any 67-73 A body will work, and '74 should work. 75+ would require adding the mounting locations for the early bumper brackets.
