Missing RPO codes??? looked everywhere

I have an 85 IROC-Z that I am trying to decode. There are a few codes that I can't seem to find anywhere. they are G5C and G6C. these codes are clearly visible and are followed by a common GU6. Has anyone seen these before? There are also a couple more that I can't find but couldn't remember which ones.
thanks for any help...
