yellowsub54,
Fryer\'s has a lot of patterns and colors (they did not have '54/'55 Chevy suburban). They are in/near Vancouver, WA.
If they do not have your pattern, they will take your old covers as patterns. They will try to match your colors, too (if they do not know them).
Gilbreath Upholstery Supply has a wide variety of fabrics (if you need to match colors and texture) and other materials.
