Hey Eric, I know Pontiac did make the Nodular rears with the N cast in them. I owned a 68 GTO that had one in it. It also was a 3.55 posi. As far as the bird rear, I have owned about a half dozen of them dual bar rears/cars and have never seen or heard of one(nodular rear) in a bird. But, obviously they made them. I just keep on learning.
I assume it must be rather rare...the Pontiac site might be a good source to check. Let me know what you find out, ok. Cool stuff !! Max
