Hi all, i have a 1956 Buick Century 2 door Hardtop in Australia and we need some help trying to decode the trim and paint codes. Paint is... CGC-1 and the Trim is...621. These are the numbers on the id tag on the passenger side of the firewall (car is LHD). The car is unrestored and has been in Australia since 2005, and there is not alot of info over here for these vehicles. Can anyone help us??
