Correct me if I'm wrong ,but I thought all 55 Nomads are Bel Airs? I looked on a parts site and they had a listing for 55 chevy Nomad BelAir and a 55 chevy Nomad base. What with that?!? So, am I wrong? Did they have a 55 Nomad that was a non-BelAir? I've seen a lot of 55 Nomads without eyebrows. Were they taken off or is it an option?
