I've always been partial to similar era pieces when original parts aren't used. Gbodys are boxy and have a lot of straight edges. Curvy, modern consoles and seats look out of place to me. I had a set of mid-80s Cavalier seats (power driver) that would have looked right at home in a G but sold them to make room for a move.
You can make just about anything fit but making it look right seems to be a bigger challenge.
