1958 was the only year that this body style was produced by Chevrolet. That
was a huge capital investment just to produce a single year of production.
Is this body style derived from the 1954-1958 Olds, Buick shell? Probably
only an oldtimer could answer this question.

I have an article from the "Collectible Automobile" magazine about the
58's. Unfortunately it's home and I'm not right now. However, from
what I recollect of the article, the 58's were an all new body that
shared nothing with any of the previous years.
