Those are Argentina Novas. We have a member from Argentina with one at stevesnovasite.com. His screen name is martinchevy73. He has shared a lot of very cool information on those. They are called serie 2 and other things like that. The oldsmobile style wheels are factory ... they all come with six bangers but those guys do alot to them. The instrument clusters are really cool. I have seen a picture of a Nova from Africa that is a factory hardtop which they never made here. GM offered some neat stuff across the pond.
