Hi Jenny,
Thanks for your offer of help. On my 1958 Chevy 3200 (still has factory paint) there isn't a paint code on my ID plate. It is simply stamped "SPEC" which I assume means special. I did look at some '58 chips a while back and it looks as though my truck is painted two-tone Bombay Ivory and Anniversary Gold (which is a 1958 car color). Can you cross reference into paints currently used? Thanks again, Jenny.
