This fin stainless will fit all 57 Bel Air models including Nomad. The moulding inserts are there along with the fins. There is one picture with one little ding in one of the mouldings. The right person can take that out. Before you put them on the car put a little grease on the balls and the mouldings will go on and come off easier. They do need a polish but are reasonably shiny now. I do need to put them in a tube “pvc” so I put 40$ for shipping.
