GM Master List of RPO Codes
This doesn't have 100% of the RPOs but it is one of the better ones I have found. It might have been posted on third gen before. Check it out.

Re: GM Master List of RPO Codes
I've had this list for years and found that it doesn't have the few codes I got it for. A friend at GM sent it to me when searching for 1C5 and a few others. I have the original paper copy. Oh well.
