Attached is the only GM list of RPO Codes and Definitions that I have left. The others were lost awhile back in a Backup hdd failure. But they were not as handy. This one is over 400 pages and seems to be comprehensive but many RPO Codes on my vehicle's label are not represented in the list attached here as pdf.
Hoping others might chime-in with other pdf versions of GM RPO Code lists.
