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.
There may be additional interior codes for Oshawa-built Chevelles as I have no source to reference.
