I worked at the Chrysler McGraw glass plant making those darned things, other than being big and heavy they were gravity formed not press bent like the corvette . So I think it is really close to the same curvature. It maybe a little less than the corvette since the corvette has a compound curve by being formed by a male plug to a female ring piece of glass, where the barracuda has just a flat"ish" curve due to the way it was bent. the longer straight sides are not an issue once you make it around the curve going down
