Second Gen Dash Question....

[70TWO NOVA]

Ok so my dad and I are restoring an 80 Z28. We both like the looks of the earlier "wraparound" style gauge cluster and dash as opposed to the later flat dash the 80 came with. Our question is what years did the dash change from the early style to the later style, and can an early style go into a later second gen without modifications?

We want to go from this style....

to this style....
