Guys-
The Cd for the coupe is 0.29, 0.33 for the hardtop, and 0.38 for the
rag-top. I got that from Chevrolet printed documents. But they they won'r
specify frontal area, even though I've tried Chevy people (at least, not
the right ones). So 19.38 or 19.75 square feet seems reasonable? I think is
too big.

Subject: Re: Frontal area
You are correct if the vette is a Coupe. The coupe has an indention in
the roof to direct airflow over the car. The fixed roof is slightly
higher as it is flat & the rag top, well, it's a rag top......
