My reference to the 1977-81 styling was in response to a post that implied Chrysler was in the lead with styling, which I'm pretty sure is universally accepted as NOT being true.
Mopar styling has traditionally been 1-2 years if not an entire generation behind.
Engineering OTOH has traditionally been at the forefront. Unit construction, torsion bars, electronic ignition, rear truck doors, etc.
The possible two leading styling exceptions would be the 1957 Fury, which caused gm to do a 1 year only 58 platform, and 1994 Ram, which caused ford to design a totally new truck and split the 150 and 250 and up lines.
