Customs 1957 Cadillac coupe deville needing fender skirts

My first post. Picked up a 57 coupe deville and want to runs skirts and start to make some mild custom adaptions.
I know they did not come from GM with any skirts but does anyone know what a close match would be to manipulate into place.
Thanks a bunch

 

if your good with sheet metal you could build a set. eastwood has a tutorial on how to make running boards. really just quarter inch tube welded together and skin them. should be rather easy on the caddy not a real large surface. by the way very nice car

 

just did a search and came up with a couple different articles on how to build them. put in 57 caddy fender skirts. hopes this helps.
