The interior trim color code is a 3-digit number. Those not checked under Bucket are bench seat styling.
All U.S. plants except Baltimore and Fremont have a dash character after the 3-digit trim code number.
Fremont also adds a single letter after the 3-digit trim code to specify the interior paint color. See FREMONT at the bottom of this page for those letters.
For convertibles built at the Euclid plant destined for either Atlanta or Kansas City, and convertibles built at the Van Nuys plant the convertible top color immediately follows the TRIM code. See the paint code page for convertible top colors.
There may be additional interior codes for Oshawa-built Chevelles as I have no source to reference.
