Bumpers on 74 A-body

I'm looking at possibly buying a 74 Duster. I've ony seen pictures of the car, but is it my imagination, or did the bumpers on the cars increase in size every year. By the pics, the bumpers look massive. I'm still working on a 70 Swinger 340, but it's always nice to have another waiting project. (kinda of a sickness I guess). Howard
