Most of my experience has been with either specifically 62 or 72 B bodies. I late last year picked up my my first 62 A body lancer. I wonder if anyone else has made this observation, the Lancer structurally frame unibody seems to be a better design rendition, IMO then the 62 and later B bodies. I believe one explanation might be the A's were the first design, and fewer corners were cut, whereas the 62 b's were a later design of Mopar's trendsitting unibodies. This includes the K members, the front and rear frame rails, gussets, etc Anybody seen this difference? I am surprised they are much lighter, as the sheetmetal thickness seems greater on the structure.
