I found a website that had an RPO list that I really liked, but I couldn't copy/paste it. I emailed the link to my bro and he did something to be able to get it. Anyway, here it is. It's the most complete list I have found, maybe you can copy/paste to a text document saved on your puter for future reference.
I tried to put the list on here but, but it was too large - "The text that you have entered is too long (180058 characters). Please shorten it to 50000 characters long." I put it on my CarDomain page, so copy/paste and save for future reference!

Just evidence that the codes are pretty much universal for all GM vehicles.
