Thanks for clearing this up.

Yes, to get a 4.56 or 4.88 in a Camaro, it was a COPO order.

Comparing it to other models / years isn't really a valid comparison since the ordering method changed. The data on other 69's says this axle date was *way* off - I've always been surprised by how close the dates are on some unusual components in 69.</div></div>

Is this true for a 1968 ordered car??? For a 4.56/4.88 rear axle it had to be a COPO order???
Or only a 1969 ordered car??

Thanks in advance
