Interchangeable bumpers?

Well i had an accident today! Long story short it wasnt my fault but i ended up with a smashed grill and bumper on my -72 valiant. So i seen fiberglass bumpers being sold as to fit 67-72. I have a guy that has the 69 bumpers ready to sell. Would that one fit my -72. Its only the front im talking about. The back bumper i know differs from different years with reverse light etc. Hes far away so i cant go and look at it and compare. Thats why i ask you A-body gods here :)
