Default Rpo Codes

Where can I go to find a list for a 2007 GMC Sierra SLE truck? Ive done some searching only to find some of the codes arent listed and some are not corect. Example- G80 is a locking diff on my truck and the listings I find say limited slip. Even the engine code said I had a 6.0 diesel when Ive got the 5.3! Truck hasnt been wrecked according to car fax so Im thinking either Im not finding the right site or someone has changed the glovebox with a different Rpo sticker.

Thanks for any help.
