-NOVA- the real 4 letter word
As stated earlier, the first pic is a 73-74 with a 68-72 front end.
IMO, the 70 Duster did look an awful lot like the 68-72 nova, but...
All novas are sedans with pillars.
Dusters had record setting curvature to their side glass and were hardtops.
I also think the 73-76 Duster looks a LOT better as a re-skin of the 70-72 than the 73-74 nova does versus the 68-72.
I've had several people call my plain white with no stripe 73 Satellite a "Starsky and Hutch" car.
Torino is square and sharp, Sat is curvy and smooth, yet both have the same vibe.
