I just bought a 74 Coupe De Ville like Snoop Doggs green 74 icky sticky coupe. I know he has 14x7s on his but does the car need any mods before they'll fit? If anyone has a Caddy like it with 14x7s. let me know what you had to do to make them fit or if they went right on. The car has skirts and I want to leave them on. Thanks for any help.
