I hate meaningless replys like the one I am about to make but...
I didn't think they were. I have owned a 78, 04 and now my 86. But my 86 certainly looks wider outside than my 78 and inside I can't notice a difference. It is also much heavier than my 78 but really isn't any different. So good question.
Guess it might be cool to say it is a wide body.
