I hate to differ with Rick, but the 69 Camaro assembly line flange is egg shaped, not round. If you stand in front of the car, and look at the engine bay, it is round from about 11 o'clock to about 7 o'clock, with a consistent width between the inner and outer circle, but with from 7 to 11 is thinner, giving it the egg shape. This flange is being reproduced, too.

If you do a search over on Camaros.net, kevinw did a great post several years ago, on the differences, including some really good pics. There are some more subtle differences like a notch in the horn, on the originals, that are pointed out.
