camaro/nova frame interchange

[inetquestion]

The frame on my 69 camaro isn't usable for a restoration due to rust pitting around the battery box. I was under the impression that a 68-74 nova frame was exactly the same on a 67-69 camaro until yesterday. A local shop that does restorations told me they are close but not 100% the same and I would have a hard time getting the body lines to match up. Can anyone confirm this?
