I have a 72 SS. The build sheet has option ZP3 SPECIAL PAINT. The cowl tag has a '-' where the color codes should be. On the bottom of the build sheet a paint code of WA-4027 BLUE is listed. Does anyone have a translation of this code to a GM color?

According to our PPG super computer, it comes up as Atoll Blue, PPG # 2166. Atoll blue was a Pontiac name, used the same color as Chevy's Fathom Blue. I was under the impression that this was a standard color for 72. Maybe not???
