Does anyone know where i could get original design seat covers for a 65 Coupe DeVille, i want re-apholster my interior and give her the original look she deserves.

Hi Kaotickid7
standard upholstery was "leather and cloth", leather options was available at extra cost.
Do You have the trim code number? It's very important to match the right colors.
