Yeah, I have pictures on here on one of the '73/'74 bumper threads, but the bolt hole locations from the bracket to the bumper are different from '73 to '74, so the brackets are actually a bit different. I believe the crash reinforcement beam behind the bumpers is different as well, and the '73 brackets might be shorter to pull the bumper in. I haven't compared them side by side but they're all visibly different, they're all one year or even half year only stuff.
