Hey Rich,
Grady and I were talking about this today and were specifically discussing correct a/c filter elements and Grady remembered detailed photos of the l78 nova. I am not sure it was a Harrell Nova. Article was posted on here within last year.

Looking for examples to support what I think is correct ac filter element for my 06A built Baltimore Chevelle SS. My phot below was taken 2nd day after delivery and looks to me (Grady too) to be a diagonal mesh, diamond (not square) shaped mesh.
This a photo of another L78 '69 Chevelle with what appears to be a similar diamond mesh screen.
