Some folks may not like this, but it's not that A bodies have less quality. It's the cars built around 67 A bodies, and 68 B Bodies. I have a 64 Sport Fury, and owned a 69 Coronet 500. The quality was way down from the 64. First thing you notice is the later doors sound like a tuna can when you shut them. My 69 340 swinger is the same. That doesn't mean I don't like them, cause I do. It's just my 64 just overall feels much more solid.
