This set will do both front fender stainless spears.
This set will work if the fenders are already on the car. The push in clips allow the spears to be mounted without removing the fenders due to obstruction from the cowl and air ducts.
This set has all 14 clips, I have noticed sets out there with only 10. There are 7 holes per fender on a 1957 Chevrolet.
Fits all models, of Bel Air or 210.
