Is there any issues in regard to the non-staggered shocks with swapping a `72-`74 Nova 8.5 rear in a `67?

I was just reading one of my old Chevy High Performance Magazines the other night as I was contemplating finding an 8.5 rear to replace my 8.2. I instead located an original 1968 12 bolt posi rebuilt from end to end for $850 so I jumped on it. I cant seem to locate it as it would take me awhile to filter thru them.
But what I can remember is the perch's on them were the same all you had to do is re-use the lower part of the perch from your original rear to bolt on the leaf springs and the shocks should bolt right up. They said it would be a direct swap and almost as good as a 12 bolt, and way stronger than the original 8.2.

Good Luck
